How to play this kind of table?

Hello all,

I've played a couple games of NL Texas Hold 'Em with some of my friends (6 total) and after a bad beat last night I'm frustrated and wondering if I should change my strategy. I would characterize the table as pretty beginner level: people call too many bets, it is rare that there is a pre-flop raise. I would say it's generally hard to bluff because people call a lot even with bottom pair, and people tend to underbet a lot too (20% or less of the pot with top pair top kicker with no flush or straight) which can make it hard to put them on a hand. People call bets rather than reraise all the time, but will call reraises if you do it to them. I decided I should try and get in to see the flop cheap with almost anything, from most positions because I am unlikely to be raised, wait for a good hand and let them call me all the way down, maybe slowplay it if I flop an absolute monster and try and let them catch a little something to bet with. Well, I got one good hand all night while someone else was always getting two pair or trips. I got whittled down all night trying to catch something and finally went all-in fairly shortstacked from BB with only limpers with A10o 4-handed, got one caller with 910s and lost when he caught a 9 on the river. Anyway, what are some ways to do better at this table? Thanks for any advice...
