As an altoholic, the best way to contribute in AvA is healing or is there another way?
Siege weaponry hits the same regardless of level. Magicka pool/recovery will be lower. You're heals won't be as strong but they will be more effective then trying to dps and getting dropped at the front line and hoping for a rez.
Join or follow a bigger group. Resto staff with regen and grand healing and their morphs is about all you need if you don't plan on healing end game. The full channeled auto attack with resto staff will also return magicka to you; if you're low oom and there's someone in range to hit.
Everybody's playstyle varies so if it doesn't suit you; you can try something else. Just be prepare for it to be a bit more brutal as a lowbie.
