$22 Early Levels preflop hand selection

[DEVY]

Hi all, after reviewing my SNG play i have decided that there are holes in my early game preflop play(levels 1-3).

Currently im raising 4xBB with QQ+,AKo AKs,
I am limping with all other pocket pairs and only calling raises that are less than 1/15th of my stack.

Should i expand this raising range to include AQ, JJ and TT.
Should i raise more with limpers. What about suited connectors?
