I think the best advice I've heard about jumping lately was bend your knees. What do you mean, I already bend my knees! Well, my coach explained, you're only bending them about 50% of what you probably think you're bending them. So even if you're into your knee it's probably not enough. This will get you more power on a loop and I'd guess that when you tack one onto another jump, you're already bending from the landing. Also, with the loop and any jump, while you bend your knees make sure to keep your hips under yourself - don't stick your bum out.
As for the right side thing I'm not sure if I'm understanding. Do you jump over your right shoulder? If so I wouldn't think about rotating from there too much. You don't want to push things out of alignment. Make sure your shoulders aren't getting out of alignment with your hips.
