First of all, the way to post images is to register an account with a site like www.photobucket.com (its free) and post your images there, then you can link to them from here using the image tags that it supplies.
It is a nice looking sword, there are two ways to texture it.
The first way is UV mapping. You have to do it this way if you want to use the model in game with a texture. There are many UV mapping tutorials so I won't explain it here.
The second way is simply assigning a material to different parts of the model. To do this, go into edit mode, go to edit buttons, select new under the mat buttons. Then go to materials tab, and choose the material you want from it. Select the faces you want to have that material and click assign. It sounds kinda complicated but it is really quite easy to do.
