Disconnecting the deck is no biggie. As for connecting, I never mess with the wheels (mine are set somewhere mid-height), I just leave them as is and drive the tractor over the deck with no problems. But connecting the shaft is the major league pia for me, it just flat out sux. The best method I found to mate the shaft with the pto is to rotate the shaft using the deck belt, that way it rotates the shaft very easy as opposed to having to rotate it by hand. When I feel it catches the splines of the pto, then comes the struggle pulling back on the snap ring to slide the shaft on. I haven't found a good technique to make this process easier, hopefully it will come to me.
One thing I found on the deck, the housing holding the slide pins can get bent a little from holding up the deck, off-setting the pin a little bit so that it doesn't line up perfectly with the hole in the tab it's supposed to go in. If you notice it's hard to pull those pins out when you're taking the deck off, it will be even harder to put them in fully when you're mounting the deck, and the following time they won't even fully engage with the tab...meaning your deck is not properly attached to the tractor. If you see that happening, the simple remedy is to hook a pry bar or something along those lines under the pin, using the fin (just underneath my thumb in that pic) as leverage. Just pry up on that pin, which will bend the housing it slides in enough to line it back up with the tab. The pic shows how the pin wasn't going fully in the tab until I bent the housing back into place.
