i've already played PS:T, i thought it was an awesome game (story wise anyway) but i was forced to quit at the boss fight where the planes merged together or something, was a year ago so i don't remember
Damn! You were really near the end! You quit because of a game glich (that fight tends to glich) or because the combat was an issue?
I bring it up because BG2 and Planescape Torment have (almost) exactly the same combat system.

also i still have no idea what AC and THAC0 do :/
THAC0 = To Hit Armor Class 0. What THAC0 does is tell you what number (between 1 and 20) you would have to roll for you to hit a character with Armor Class (AC) 0, which is a fairly good AC.
For example, if your THAC0 is 20, then you'd have to roll a natural 20 (a 5% chance) to hit a character with AC 0. To hit a character with AC 10 (the worst AC possible), you'd have to roll a 10 (because 20 - 10 = 10) or higher. To hit a character with AC 5, you'd have to roll a 15.
Thus, the lower your THAC0 gets, the easier it is to hit AC 0. If your THAC0 is 10, then you only have to roll a 10 or better (a 50% chance to succeed) to hit a character with AC 0, and you'd only have to not roll a natural 1 (critical failure) to hit a character with AC 10. And you'd have to roll a 15 to hit a character with AC -5.
Since everything is based off of AC 0, the lower your AC is, the better. If you can make it to AC 0, then you are very difficult to hit. If you can make it into negative numbers, then you're even harder to hit.
Anyway, I hope that explains why it is better to have a lower AC and THAC0. Now, the only time this really comes up is during equipment (otherwise you have no control over your AC or THAC0 after character creation - they remain constant unless altered by equipment or level increase). However, if the manual has been confusing you with the terms, now you know what they mean.
