I remember weaning my son at 14 months, and it was a little sad but a really important stage of our development. It gives your child independence and gives you back your body! This comes at a time when you need to re-connect with your husband too, so that will be good for everyone.
I would probably not try to wean and move him into bed at the same time, unless you're wiling to go cold turkey and have some sleepless nights while you're doing both. I would probably move him to the bed first, using the nursing to calm him and get him back to sleep. This may take some time, but you can also cut down on your nursing during the day (just cut out one feeding at a time, gradually going down to just nursing at night and then finally eliminating that. You will have to pump during this time but eventually your milk will decrease and stop). But I don't think I would get down to one nursing at nignt until you have him in his own bed for at least most of the night.
As for getting him into his own bed, just be patient and know it's going to take a few weeks at least. Start by staying in his room while he goes to sleep, no matter what it takes--nursing, laying with him on the floor, letting him fall asleep with you there, whatever you have to do to keep him there rather than in your bed. Then do the same when he wakes up at night. I have a friend whose 18 month-old wakes every morning at 4 and they bring him into bed, where he sleeps until 6:30. That may be your schedule for awhile, and then you can try to get him to sleep in his own room full time. This is worth doing for your own sleep and sanity, especially if you plan more kids!
My main advice is to be patient and take your time, don't expect it to change overnight since he has been doing both these activities for a full year! Give yourself 4-6 months and go slow. You may be surprised how quickly it goes, even with that kidn of a deadline.
Good luck!!
