If these are trouble hands for you, just don't play 'em. My premium hands JJ+, AK earn like 2 BB/hand. SC's and connectors earn on average about .1 BB/hand or less (and I don't play them very often at all). There's lots of earn rate to be found outside of connectors, suited or otherwise. Just ignore them except in the big blind, when it's limped to you, and play them as well as you can from there until you get a feel for it.

Not playing sc's at all is not a big leak, imo, especially at microstakes.
