AV Uncapper is super-useful once setup, but it does have some of the most nonsense documentation of any mod I've seen. I've taken university level calculus, but when I'm setting up a mod I don't really want to have to break that out

.
Make sure you also download http://www.tesnexus.com/downloads/file.php?id=35675 which allows you to set the AV Uncapper settings via an INI file rather than messing around with script in the construction set. Use its included ESP file instead of the one included with the original AV Uncapper.
Here's an INI file that I've modified from mine to do what you said:
; ===============================================; ====== Actor Value Uncapper Settings Ini ======; ====== This file belongs in "Data\Ini" ========; ====== AVUncapper by JRoush, ini by JCN =======; ============== Ini version 1.01 ===============; ===============================================; NOTE: Refer to the AVUncapper manual (AV Uncapper Features v1_beta1.pdf) for in depth descriptions of all functions.; ===== PRESETS =======================; Note: The rest of the INI will be ignored if using a preset.set JCNAVUncapQuest.iavuUsePreset to 0 ; 0: Do NOT use presets. ; 1: Uncaps all stats and skills, allowing them to level past 100. ; 2: Uncaps all stats and skills as well as enabling diminishing returns for Chameleon, Reflect Damage, Resist Normal Damage, Spell Resist, Spell Reflect, and Spell Absorb.

I changed it like you said to make the maximum you can get through levelling to be 100, instead of the 200 default. I don't think there's a way to limit how high things can be fortified, but due to the way AV uncapper works going from say 150 to 200 is a pretty minor difference. Edit: to make it so that you can level to 150 instead of 100, just change those two lines near the top.
Other changes from default settings:
I changed chameleon so that 100 points of chameleon gives you closer to 95% rather than the 85% of default AV uncapper. If you want to reverse this just change the 3.00 and 0.35 back to 1.12 and 0.83.
Alchemy is set to use your current (fortified) level, rather than your base skill level. I believe this also adds the bonus from your luck ability.
Reflect Damage is set to reflect 50% of the damage from arrows and similar projectiles. To reverse this, change the 0.5 near the bottom back to 0.
Block's maximum effectiveness is increased from 75% to 95%, and max armour rating from 85 to 95. Those settings are also at the bottom.
Be aware that AV Uncapper can have some surprising effects on game mechanics if you haven't read through to understand the documentation. For example, fortifying a skill skill from 100 to 120 should give you
far less than a 20% increase in abilities.
Hope this helps
