Trouble at the Tournaments (Online)

I don't know if anybody saw any of my other posts somewhere down the line about always being at the bottom of the tournament placings, or struggling along with the raising the blinds.
I play a fairly tight game. I normally raise with Pocket Pairs TT and above, and I limp in with high, connected (suited or not suited).
Would playing suited connectors open up my game some more? I know that a lot of players like to play A8 or A9, something with an Ace, just because it is an ace. By suited connectors, I'm talking about cards like 56s, 67s, 78s, 9Ts, and up.
I'm trying to figure out a way to loosen up so I can be a part of the chip leaders and make my way through tournaments without a problem.

Even tonight I played in a poker tournament for my college. Out of 60 players, I placed 9th, but I got squeezed out by the blinds. I played 45 one time and got a straight, but I think that was total luck on the draw of the cards.
