As far as cages, I have the sturdy cage from Suncoast gliders. It has a hammered powder coat finish and is easy to clean. They charge 9.95 shipping. Cage has to be assembled. My second cage is in our RV and will be replaced soon. Not worth mentioning.
I have 2 different glider safe wheels. One from attic works (my girls favorite). It is cage mounted. One from Spinzone. It is a floor mount.
You will need a cage set which includes 2 sleeping pouches, corner hammocks, and a bridge. I would recommend finding a set with larger sleeping pouches so it can grow with your joeys and as you develop your bonding process, you can spend some fist time with them.
You will need a bonding pouch and blankies (4" square pieces of fleece to put your scent on (tuck under pillow or toss in laundry hamper) so they can be tucked into their sleeping Pouch while they sleep.
I currently use the Critter Love complete diet. The best DIY diet is the BML diet. Everthing can be purchased at a grocery store and a pet store.
I don't have any other pets, but I would recommend that you keep your gliders in a room away from your cats until they at least settle, and your bonding process has begun. Too much stimulation in a new environment is very stressful. Many here can tell you their experience with other pets, but I would not risk it.
I have given you a lot of info. All words in blue can be clicked on and will take you to more on that topic.
The more research, the more questions you will have. Scroll down to bonding and relations topic. There are a few really good reads there.
Good luck and keep us posted!
