I just started 6-max, too, but here's how I play it generally:

Axs utg -- raise

JTs utg -- raise

KJs on the button facing a raise -- read-dependent, but generally raise in light of my position.

KQo facing a raise -- on button, same as immediately above. Otherwise, mix between fold/call.

AJo facing a raise -- on button or co, raise. Otherwise, still usually raise but occasionally call.

Opening from the CO with Ax -- raise.

88-99 facing 2 limpers in CO -- raise.

Seeing a trend. I think most of these are raising situations when in position. Makes the rest of the hand easier to play.
