Poor little guy! Gas is no fun.
Keep up with the burping and do some tummy massage and bicycle his legs to get that air out. You could try cuttig out dairy or some of the other common culprits - every baby is different, so you'd have to see if it helps or not.
Gas can also be caused by a very forceful let down reflex, because the milk comes out so fast that the baby ends up gulping a lot of air. Have you noticed that he sputters at all on the breast or gags when your let down starts? Thrush can also sometimes cause gas - how are your nipples feeling? Any pain?
As for the frequent wakings, it could be a growth spurt (they seem to happen constantly when they're young!). If so, it should taper off in a couple of days. It could also be that the discomfort from the gas is waking him and he's just sucking for comfort, not really for food - does he take a full feed at these times?
