FCOM sounds good, does it includes some fix to those attribute gains i mentioned above or is this mod http://planetelderscrolls.gamespy.com/View.php?view=oblivionmods.detail&id=334 compatible with the bundle?
The intention of this mod is to fix the annoying parts about Oblivion's Player leveling / advancement system and keep intact as much as possible in the spirit of the original game. To create a mod where you can play it and have fun and not worry about micromanaging X5 Multipliers, and be able to level up a character and not "GIMP" him by not training the right skills at the right times...that's exactly what i am looking for

Oblivion Xp sounds fun but it moves it too much for me

I like the experience gain in general i just don't like the micromanaging of the attribute multipliers and constantly worry if i get them x5...
nGCD or Realistic Leveling might be what you're looking for. Both remove micromanaging completely, the leveling is seamless and in the background. Both require OBSE, but so does lots of excellent mods. I'd also recommend Progress, which governs at which rate skills level and comes with several neat plugins.
FCOM is great, but rather complicated to set up so perhaps not the best choice if new to mods. OOO and MMM give much of what a complete FCOM install does, but easier to set up. I'd recommend starting out with OOO/MMM if so and then "upgrade" to FCOM perhaps - once you have OOO/MMM installed/running correctly and more experience with installing mods, handling load orders etc.
EDIT: I should also add that I'm a bit partial to OOO/MMM/FCOM as that's what I'm playing, but there are alternatives, such as ROM and Oblivion WarCry New Dimension EV, both of which are even more comprehensive "compilations" than OOO, affecting much of everything (ROM comes with its own version of Realistic Fatigue (which is an excellent mod as well) etc., for example. ).
