Good going! 5 gallons batches is the way to go IMO. I'm moving this thread to the beginners forum area because this is the Off Topic (meaning not really related to brewing) area and you will get much better response (much less smart-assery) in the proper forum.
For myself, I recommend your local supply place, or any of the major online suppliers. They will have a wide selection of equipment kits and also recipe kits. I'll mention a few online places by name, but by no means is this a complete list, nor is it an endorsement of any particular supplier.
Northern Brewer
Midwest Supplies
MoreBeer
etc. etc.
There's many out there and most of them are great to work with. You can even check out the review area in case you want to see what others think of a particular place.
A basic kit will contain a fermentor (bucket, better bottle, carboy) and a bottling bucket (bucket with a hole for a spigot) plus airlocks, sanitation chemicals, bottle wand, etc. The prices will vary based on your personal choice of fermentor and added extras (don't worry, this is just the start of your habit of picking up that next needed piece of equipment!
I like buckets, and I think I do perfectly fine with them. They are light, easy to carry, and easy to clean. Others prefer better bottles because they are see the fermentation taking place (I know what it looks like and I don't have to peek at it constantly), and other prefer glass carboys for the same reason and for the added benefit of having approx. ZERO oxygen permeability (Though I think any of th3e options are fine for O2 for the length of time your beer will be in them, if you are careful when racking.) Lots of people use glass, but they have been known to break and cause significant injury, usually unexpectedly. That said, I almost always use my glass carboy for a long secondary on big beers. Just my choice.
Anyway, good luck and hoppy shopping!
