So DS needs surgery again

We are scheduled for next week.
Nearly a year ago he had tubes placed in his ears because of chronic, undetected ear infections. Well one of the tubes fell out and already he has so much thick fluid built up behind that ear drum that it is actually pulling the eardrum in - not good.
His speech therapist has also been suggesting I have his adenoids and tonsils checked because of his chronic ear infections, mouth breathing, excessive drooling, etc. At the ENTs today he said the tonsils look fine but he needs to have the tube replaced again and the adenoids need to come out. This is an ENT who has a reputation for NOT being surgery happy yet both times I have taken DS to him (not including follow up visits) he has said he definitely needs surgery.
I am not questioning the need for surgery, and I know what to expect with the tube surgery. And I saw a big difference in his speech after the surgery - much more words and clarity in the words since he was now actually hearing properly. My questions are about the adenoids surgery. Doctor said it is a little harder on the kids and takes a bit longer for them to recover.
1. What have other peoples experiences been with this type of surgery? what kind of results did you see?
2. How long should I expect to keep him out of daycare - it is on a Thursday and I am planning for that day and Friday. Should I also expect to keep him home Monday?
3. What types of foods/beverages do people suggest for following the surgery. Any I should avoid from your experiences?
Thanks in advance to all!
Re: Question for STM+
Eta: spelling
She had her adenoids out and tubes in at the same time. So it's hard to know which helped what. It did dry up the drool and constant colds, making her much more pleasant to be around. Her family definitely was glad they did it, and wished they had done it sooner, her case was pretty severe.
Forgive any grammar/typing errors, I'm on my 2nd motn feed.
