(LC) Looking for some live poker advice

Going to play some live poker tonight on a table of about 9 ro 10 people. Most really don't know how to play (some will limp JQo UTG). I am just looking for some basic advise because I realize live poker and SNGs are quite different...

Should I expect them to respect a check/raise? how should I play post flop? should I limp with raggy hands to see what flops?
