Go for a kit that has a glass carboy for secondary, and wort chiller.
Look into getting a brew kettle that will boil at least 3.5-4 gallons if you can't go for a full boil. The larger volume gives you better finishing beer. Full 5 gallons might put you outside. I was doing about 4 inside, but it did take a while. Don't forget to leave room in the ketttle for foaming, especially if you like wheat beers.
I got my kit from homebrew heaven. It was pretty complete. Sanitizers, bottle washer, chiller, brushes, thermometer, hydrometer, plastic primary, glass carboy, I really didn't need anything else to get started (other than a brew kettle and something to stir with) You can even get your first kit at a discount with the order. My only complaint was the primary bucket was a tad on the small side. I ended up drilling a hole in it and use it as my bottleing bucket. They do offer a kit for kegging.
I definately recommend trying to get everything from your local brew shop if you can, but their kits are pretty complete and inexpensive, best I've found so far.
