i have been going through exactly the same with my 7 mo. and he is starting to be a little better as he seems to be mastering crawling during the day. what i have found is that for me, i just have been accommodating him at this point because i know that this too shall pass. sounds like you will have no problem getting back into things once this phase is over. i have been continuing to put my boy down in his bed, but when he gets mad and its clear he is over it, i bring him to my bed where he sleeps better -- especially once i am in it. but i also know that i will keep putting him in his own so that i can let him be back on his own when he is ready.
for the teeth, hyland teething tablets do work, you just have to give them consistently.
from my experience with my first, sleep issues are not a battle, it is all just a transition. we get to choose if it will intense and frustrating or gradual, nurturing and time-consuming! know that it will all be different soon enough.
