I would consider them very minor. I have had Fallout 3 for about 4 months now and have had less than five problems. Most of the errors are graphical and there is also a small problem with getting stuck in the landscapes, but other than those, I haven't had any that REALLY affect my gameplay.
Yes, you can install Fallout 3 PC mods from Fallout Nexus onto the PS3. For a tutorial, see: http://fallout-mods.blogspot.com/2010/11/fallout-3-mods-for-pc-on-ps3.html
To mod Fallout 3, you must download the G.E.C.K. from the Fallout 3 official site. You can not download it for PS3. I've tried myself.
