someone please correct me if I'm wrong, but every time I "knit with 2 strands", I just hold them together (strands lying side by side) and knit as if it's only 1 strand. no twisting.
as for "right side" and "wrong side" - sorry, I suck at explaining things but I'll give it a shot - for example, if your pattern is in stockinette, the right side would have all the little "v"s and the wrong side would look like garter stitch.
HTH... good luck, tab.
