The GAC card will probably not be a big help for the lines - but fastpasses will work great.

That is correct. The GAC (Guest Assistance Card) is not meant to eliminate or shorten the wait in lines - it actually says that on the card. The card also mentions that if you do want to shorten your wait in line, you should use Fastpass. The GAC is meant to assist the CMs to know what needs someone with invisible disabilities might have. So, it is not going to help much with the lines, and in fect, if his problem is "stamina or endurance", the CMs will suggest renting a wheelchair or
ECV. For someone using an ECV or wheelchair, a GAC is not usually necessary. Most of the lines/attractions are wheelchair accessible and, since the CMs can see that you need an accessible entrance, you will be directed to the correct place without a GAC.
You can get more information about GACs and renting wheelchairs/
ECVs on the disABILITIES Board in the disABILITIES FAQs thread located near the top of the board.
There is also a link in that thread to the official WDW Guidebook for Guests with Disabilities, which lists all the rides that have warnings. No one will stop him from riding, but IMHO, I would not ride anything with a warning that soon after coming out of the hospital. I agree with Pixiedust34
I had my gall bladder removed 3 weeks before our WDW trip last year. My surgeon assured me that I'd be OK to travel in 3 weeks. He was right, though I would not have wanted to go any sooner than that. I was sore and tired, especially the week immediately following surgery.
I wasn't allowed to bend or lift anything for 2 weeks, and it's difficult not to do that while you're on vacation. If your dh went to WDW that soon after his surgery and expected to ride attractions, I'd wonder at how well he'd be able to get in and out of the seats.
Unless you stick to shows (where he would be able to just sit in the ECV) here is a lot of getting in and out of ride seats at WDW. Some are much easier than others. Even if it's not that hard, all the "in and out" is tiring.
Since he's still in the hospital, you don't really know what he's going to be like next Tues - which, after all, is only a week after his surgery. By the time you do know, it will be too late to cancel. Because his appendix ruptured, he may not come back to normal as quickly as someone who had a more simple appendectomy.
Pixie dust to you, what ever you do.
