From the learning standpoint, the only thing I'd change is:

- playing loose tables to playing tight tables

Players are still fishy even though they play tight. You don't learn much pounding 90 vpip guys that can't fold anything.

Also for 6-max, you should also experiment with LAG play (on maximum 2 tables), focusing mostly on opponents (again this is better on tigher tables, than against guys that can't fold shit).
