Get a big enough pot to hold everything at once. For a 5 gallon batch a 10 gallon will be just big enough, and most here would say go bigger. And get a big bag. I'm using a 5 gallon paint strainer and it isn't really big enough. Also, keep a friend/wife/child/sibling handy while brewing, you'll need a second pair of hands occasionally. Keep the hops away from the dog, apparently they are very allergic to them.
