This is major surgery to recover from, and your body needs time to heal. Your recovery will not be linear...you don't feel better every day than you did the day before; instead, it's often one day - 2 steps forward, next day - 1 step back, so don't get discouraged. Don't overdo anything, but do attempt things you think you can do. In general, you will tire easily during recuperation. You need to be able to nap once or twice a day.
So yes, you will need some assistance around the house, because you won't be up to resuming your normal life for about four weeks after you're home, give or take. Even then, returning to normal is going to happen at your own pace. Driving IS easier than walking because you're sitting down focused on the road, but you probably won;t do a lot of driving for the first month either, and by that time you will be walking well.
I didn't need a walker once released from the hospital. But wear a pair of sneakers of something grippy so you don't accidentally fall. Things that are hard to do, and that you shouldn't do for awhile include: Carrying laundry baskets, especially up and down stairs; climbing ladders or stools to change light bulbs, showers (baths are less dangerous until your balance is restored), bringing grocery bags in from the car. You get the idea.
Good luck.
