Pre flop odds in position?

I have a good feel for post flop, I can play very well from the flop.
One problem I really have is preflop, I feel dumb when it comes to preflop.
How much odds should I be having to call a suited connector or even offsuit broadway cards/some hand of value while in late position?
or if someone raises like 3x preflop, should I be calling with these hands in position if several people flat called the raise?
Im talking in tournament situations, should I start doing these things more in middle and late stages? and not at beginning of a tournament? Because I know your supposed to play tight at the start, but are there any exceptions?
A lot of questions, Lol. Would be great if someone could answer a few for me, or talk about what you like to do in different situations like these depending on how deep the tournament is and such.
