2 Points that you are saying and scaring me:
1) easy model maker
2) my game to be downloaded and sell
I am all for you making your games and selling them, but you really should learn a little more about the softwares needed.
You are asking questions, which is very good. BUt I don't want you to be mislead into thinking you can find a free modeling software, in a few hours (or even days) model an entire game and sell it. That would be foolish to think that given no experience.
FPSC is a wonderful program for getting your feet wet. I suggest you look at [href]www.swissquake.ch/chumbalum-soft/[/href].
It's important to read the forums at their web site if you have questions about their software. From what I read, a lot of people use this modeler program to make Entities.
I use a program called Acid to make my music as well as my sound effects. Great software.
For selling your games, you got lots of choices. Yahoo Games, Real Audio (which is I cannot remember what they are now), Reflexive, Gamehouse, and few others. I don't recall seeing any FPS's on there, but your more then welcome to try.
For movies, I use 3D Max, but it all depends on what type of movie you want to make (render or live action). Max works with both.
I hope this helps you in some small way. Best of luck!
