Well, basically I've been planning to get ZBrush for quite some time but am not sure if I should because of certain... abilities. Like for instance: How does Z brush texture (if it does)? Does it have adjustable samples of textures and can pretty much put it on an object, such as metal, human skin, clothing, etc? Or do you just unwrap and make the textures in the traditional way? Pretty much what I'm saying is can you texture not only human objects, but other non living objects (and model them too)? -SJHooks.

Look into polypainting for painting textures, You paint directly onto the model.

It has alpha's which you basicaly drag onto the model. They are also used for patterns.

Of course you can. Look at woolfman's stone bridge
All done in zbrush?

Yes you can. Mike5424 is right that bridge was all done in ZBrush. The UV/Texture/Normal/Cavity Map. ZBrush is amazing! Poly paint is really quick and easy. Just learning to switch between the things your editing is the hard part at first. ZBrush had it's own UV map for some time but it was junk. Just recently they released something called UV Master and It's tons better to use and makes it easy to edit maps. I'll find a quick video showing you the texture work side of it and UV part of it.

Update:Tons of videos showing off what ZBrush can do. Click on the tileable texture one.

The modeling thing, I was talking about things like a... sci fir metal wall, or a sword, or some gear or whatever, stuff that you can't really imagine by sculpting perfectly out of clay, as I know ZBrush does. And Woolf, does that technique of texturing apply to all textures like wood, metal, cloth, etc. or just textures such as the brick wall shown in the vid?

Zbrush has many different polypainting tools, and use of zapplink is also very helpful with texturing as well. You can also project images onto your model, which makes texturing much less of a hassle and faster. And now, with UV Master, you can unwrap your mesh as well. The only thing though, is that your polypaint goes down in quality as your polycount goes down. Programs like Mudbox and bodypaint dont work like that. But in Zbrush the texture quality goes down if the number of vertices in your mesh goes down. So you can polypaint the high, decimate it down using decimation master. Unwrap using uv master, then bake the polypaint to the UVs and then use Xnormal (free program best normalmap/AO baker better than zbrush) and then you have a game ready mesh.

The days of 'Zbrush can only be used for organic modelling' are over. There are plenty of tools inside ZBrush that can be used for non organic models.
Regarding texturing, it's always best to Unwrap a model yourself, but UVMaster does a pretty damn good job at Unwrapping something almost automatically.
For 3d painting, turn of Zadd/zsubtract in the toolbar, make sure RGB is turned on and then turn colorize on in the tools>polypaint tab. Now you can just paint on the model just like normal. Zapplink is also fantastic as it exports a render of your model out into Photoshop so you can use all the features there for direct painting onto your model. I used some custom skin Alphas on my model here which was all created in Zbrush's polypaint and then some final tweaking with ZappLink in photoshop.
Think of the Alphas as a mask for whatever you are painting onto your model, be it geometry, texture or even a simple colour. The one thing you have to remember about texturing anything is;
as long as you can paint it, you can texture it.

Well it's a different technique to texture normal items like that but it's good to know the seamless way. Alphas are really the way to go. Having a high poly model and using projection master. You can get some really clean lines in the surface of the model. Same goes for poly paint.
I don't remember who it was but there was also someone on the ZBrush forums that was making custom brushes to make hard surfaces easier to model. I'll look for it. It was really good stuff.

Look into lazy mouse, It works well for that sort of thing.

for sculpting within zbrush the the polish tool (hpolish is the one i'm thinking of) enables you to very quickly sculpt and hardsurface model. on the texturing side zbrush allows you to import any image and then apply it as the entire texture or use it as essentially a colour for polypainting, however polypainting with images often gives muddy results and so i recommend that you use the drag option from with in the drop down which shows you the 3D and 2.5D sculpting types. my main recommendation however is only using base colours within zbrush, unless you're texturing a face or something organic, as a non-organic form won't require as much eye to eye minipulation, and that's why for non organic modelling i always block out tones, or use zbrush to enhance edges, scratchs or other details, i then apply a genuin image of metal let's say in photoshop, perform some colour correction and there you go, hope this helps and i recommend that you buy zbrush you'll get your upgrade to R4 which i must say is looking very good
