I still write out my decrease instructions EXACTLY like you posted, gamerchik! Good woman!
I also agree with the others: Right side facing...I do a K2T at the beginning of the row...knit across the row as per pattern...then do the SSK at the end of the row.
I always knit one stitch first, then K2T...knit across the row as per pattern...til the last 3 stitches>SSK>K1.
The plain knit stitches at each end are edge stitches, and will ultimately be hidden inside the seam.
Making your decreases "one stitch in from each edge" creates a nice edge for later seaming.
