When your roll supports it gradually add higher stakes games. For example play 5 $1 tourneys and 1 $2 tourney, then after you get used to it and your roll still supports it, add another $2 table, lather, rinse, repeat.
This also allows you to get familiar with the players and it also allows you to acquire some hud stats to make color coding players easier.
Another thing that will help you is sharkscoping every player at the new level and use this in game selection.
If you find any good winning players at the higher stake pay close attention to their hud stats and compare them with yours.
