For the 3-st bobble rib, only the center stitch is a bobble.
Sometimes, in order to work increases into a pattern, you have to break with the pattern for a row or so until you have enough sts for a pattern repeat or a partial pattern repeat. For the bobble rib, you could make the increases until you have enough for the 3-st bobble rib. That way you won't have a bobble at the end of a row, interfering with seaming. On the moss stitch increases, keep the moss stitch pattern going at either end of the sleeve and incorporate the increase stitch into the pattern on the next row. If the second stitch in the row is a purl, knit the increase. If the second stitch is a knit, purl the increase. It helps to look at the stitches on the needle and count off the stitches backwards to figure out what that first stitch should be.
Could you edit the pattern pages please to remove page 2? We don't really need it and that way we'll avoid copyright issues.
