Hi,
I think ChrisRyan hit most of the highlights, but I'll just add my little two cents from a bit further down the road...
One way to avoid the expense of a hospital bed plunked in your living room is to put a kitchen chair next to your bed. You can use the back of the chair to push up from, which lets you use your arms to get up and down, rather than your abs. Or, if you have time to shop a little, an adult walker at the Goodwill is usually less than $10 and very handy for keeping nearby to get up and down using your arms.
A recliner is also a great option, if you have one, or if your couch is firm, you can semi-campout there, and use a strategically placed coffee table for helping you up and down.
Another GREAT help once you're home is a first-aid ice pack. If you lay it right across your incision (after the staples are out) or across your belly if you have the other kind of surgery, you'll dull down pain and swelling and be able to cope without prescription pain meds sooner.
Don't worry about taking Aunt Flo with you to the Castle. LOTS of us do - and it's sweet revenge on the ol' gal to have her evicted!
Do spend the time you have left doing things like pre-preparing yourself some easy to reheat meals, stocking the fridge and pantry with things like fresh fruit, juice, and simple non-spicy snacks. Pudding cups, jell-o, the little cracker sandwiches, etc., are all great when you know you should eat but nothing sounds good. Soup is also a great choice. Just keep it easy because you may not be feeling up to a lot of time vertical while you prepare things to eat. You need to eat to give your body the calories to mend.
Make sure you have a cup with a lid and a straw... so you can carry water around with you wherever you go in the house. The more water you drink, the less you'll have constipation and gas build up.
Also, Gas-X is your best friend once you get home, along with either Metamucil or Milk of Magnesia. You don't want to strain in the potty, it will hurt your tummy.
Pictures of extreme cases may only serve to freak you out, I would avoid them the next few days. Most of us have bad enough nerves right before we check in, anyway! Take that nervous energy and do every thing you can to make your home as comfy for your recovery as you can. Make sure you have all the spare pillows gathered up and put the good pillow cases on them to pamper yourself. Arrange small tables to handy spots where you'll be resting, so you always have a place to put a drink and snack while you're propped in case you drift off.
I was nervous about being dizzy in the shower. I went to Goodwill and picked up a shower bench for $5. My shower already comes down off the wall on a hose, so it was very easy to take care of cleanliness those first few days without being dizzy. And make sure you have something near your toilet so you can help yourself up and down without needing your abs (counter top, railing, or that walker I mentioned earlier, etc.).
Hope this helps. If you need some more preparation ideas, I'm sure there will be a hostess along soon to post some links for you to read here. Or, you can do a search up there at the top of your page.

Take care of yourself, don't push too fast. Resting with your feet up as much as possible is one of the greatest tools for healing from this surgery.
