1) Play:

AA - JJ raise any position. Reraise a raiser with AA- QQ.
TT - ~66 play for set any position.
<66 play for set Late Middle position, fold in EP or on a raisey table fold in MP.

AK, AQ, KQ, raise any position. Raise AJ, AT any position when ~7 players left. Dont call raises with less then AK.

I fold SCs because I dont want to be bleading off chips chasing draws. On RVP we start with shallowish stacks and I cant afford to blead chips. I might play high suited connectors on the button for a limp with good pot odds but I wont chase draws. Same applies to low pps, only play for cheap.

If I get involved in a pot its for a raise so I can continuation bet a safeish flop hit or miss.

I'm looking to fold, fold, fold till I get one good hand and double up. Read Rippys Sticky. Read all sticks while your at it.

Yes assume someone has the A, with more then 2 callers I check/fold KK in this situation. less then 2 callers I rep the A.

2)

I get weird with lowish pps with 5 left. I dont like playing them in EP so I usually just fold. If I want to blind steal with them I'm all in preflop cos I find them hard to play post flop. (Maybe this is just me being scared)

I'll play down to A8 but only if I'm the one opening the pot and I'm always raising preflop. Play KJ aswell.

I dont like calling/reraising raises unless I'm really strong. Basically your looking for situations where you can play with lesser cards (steal blinds etc. ) rather then playing cards directly.

I fold all SCs except if I'm desperate for blinds and in LP with a stack big enough to give me some fold equity.

As to the last little question I'm not sure what your talking about.
