1) I would definitely reccommend an indoor house rabbit. Rabbits are social animals and typically like to be where the people are and in the mix of things, so it's best to put them where they can be around people a lot. Also, rabbits can be very much like any other "regular" housepet, such as a cat. Many people treat rabbits like cats and let them have the run of the house (but rabbits must be supervised at all times out of a cage. This way too, your rabbit wont get cold in the winter, or too hot in the summer.
2) As for a hutch, I would reccomend not really a hutch, but more of a cage/ kennel. Most rabbits can be fairly easily litter boxed trained, and a wire grated bottom of a cage is very harsh on little rabbits' feet, so it's best to avoid these kinds. Instead, I use an extra large dog kennel, that had openings on the side, but has a plastic bottom, which makes for easy cleaning. As for a "sleeping area" as you called it, I've never really heard of such a thing. My rabbit enjoys sleeping in her litter box, so I don't know about that.
3) As for a pair of rabbits or solo, often rabbits would prefer the company of other rabbits to that of none, especially if you will not be able to let your rabbit out a lot. I was planning on getting a rabbit to bond with my Dutch rabbit when I got her, but she ended up hating all rabbits and just loving people. She probably doesn't know she's a rabbit. But if that works for you, go for it. It really just depends on you and the rabbit(s).
4) As for your question of "dwarf or regular" I had to laugh a little. There are many different breeds of rabbits, and dwarf rabbits are just one breed. I guess "regular" would mean anything else than, which includes a lot of breeds. All breeds have their ups and downs, since you at least know about dwarfs, then you should know they tend to be a little more energetic, and since they're smaller, many people feel more uncomfortable handling them. I have a Dutch rabbit as said earlier who is about 4 lbs. They're a good breed for beginners I think, because they're a good size, generally friendly and layed back. Just make sure to research different breeds, and you'll find just how many there really are!
Good luck, and make sure to do some more research on your own. Don't make the mistake of thinking a rabbit is an "easy beginner" pet either, because they're really kind of high maintenance to keep them happy and healthy anyway. I hope I helped out some, also a great website is the House Rabbit Society Website, whose address I think is www.rabbit.org .
Good luck, and keep us updated on if you do end up getting a rabbit!
