can't help you there - at least not yet...
no, it adds 9 kits as well (i'll probably try out chorister, adventurer and sharpshooter, and i ended up giving Alora the burglar kit with the lvl1npcs mod), and i'm pretty sure that s&s and RR adjust the original kits and true classes in different ways - nonconflicting and nonoverlapping - except:
as far as install-order discrepancies, the only one i'm noticing is that s&s opens up more alignment choices and RR narrows them down... i put in s&s first for this reason (LG backstabbers and pickpockets seem absurd to me, evil-only assassins are definitely more in line with PnP guidelines, and chaotic-only jesters make perfect sense (so to speak)) - and of course because of where it was on the easytutu compatibility list
ToBEx is awesome - i think you already have the core of it as a result of installing SCS, but if you like the look of http://www.shsforums...ds&showfile=871 (i think the full readme is right there) ... and the consensus is to stick that in before anything else (post-tutuToB-conversion).
i also think there's a good amount of sensible content in aTweaks: http://readme.spellh...me_atweaks.html
