1) On tables like this, I think that limping/limping behind with small to medium PPs is not a bad play. You want to see flops for a fair price and raising contains the risk that you get 3bet and don't get suficent odds to call for set value. If there is not much 3betting though, raising PPs has the advantage of creating big pots. The downside is though that you'll often have to let them go on the flop, so, as mentionend I really don't mind limping.
2) AQos is one of the kind of hands that (IMO) don't have much value in those games as TPGK will very often be no good. Same goes for AJ and,to a lesser extent, KQ. Suitedness improves them as you have a at least some nut potential. Due to these reasons I'd only play this hands in very good position. In contrast to this, SCs go really up in value on tables like this. And of course you are right, CBs don't make too much sense here most of the time...
