Well, if I may make a suggestion. First play through it without any mods so that way when you DO install them you can actually appreciate the gameplay even more for it. I.E. Restoration mods.
My personal preference right now "Heart Of The Force" mod. At Lucasfiles.com. Be warned that the crystals can only go into normal lightsabers and not double bladed or short.
I also have a bunch myself. Check my blogs section for the mods.
I'd recommend off the top of my head:
Anything that restores content (ho hum--waiting for team gizka SO patiently)
Final (finishing) touch
Ultimate saber mod (look for compatibility patches!!!)
and a few others.
