Help!

[perth]

Take a look at this cute little guy:

So I'm picking him up on Saturday morning, and will be taking care of him from now on. I've wanted a dog, specifically a beagle, for a while. It just happens that we have a very good friend who is moving cross country and cannot take "houdini", as he's called, with her. So it works out well. Only problem is, its kind of short notice, and I have no idea how to take care of a dog! I can't imagine it being terribly difficult, but I've never had a dog and don't have a lot of time to read up on the subject.

So heres what I know:

1. He is crate trained, but "not quite" housebroken.
2. He is neutered and up-to-date on vaccinations
3. He is affectionate and loves kids
4. 15 months old

Not a lot, I know. Heres what I need to know from all you experienced dog-owners out there:

1. What should I ask beforehand? As in, what else do I need to know right away?
2. What sorts of things should I be sure to have on-hand?
3. Any advice you can give!
4. What kind of dog food should I feed him?
5. How best does one housebreak a dog?
6. I have a cat. How do I introduce the two without having to worry that she will kill him?

I'm terribly excited, and I know I'm asking for a lot of information, but whatever advice I can get is helpful and appreciated.
