Sherilee:
As you know, I'm a new hiker, too. Other people will undoubtedly have better advice, but since they're probably out finishing their hikes and I'm home doing chores like you, I'll share some of what I've learned with you so far.

One of the reasons that I started hiking was because it doesn't have to cost a lot of money. So, my advice is on the fiscally conservative side.
Boots/shoes: This is the only thing that I think you have to have to begin hiking but you don't have to spend a fortune, either. Popular always seems to have a pair of their house-brand shoes priced at $20. If they are out of your size (as they were mine last weekend), check out the kids shoes, too. Boys shoes run two sizes smaller than women's shoes but are much less expensive. People may disagree with me about getting less expensive shoes, but if you wear them out quickly, you can turn them into shopping shoes or yard shoes. This way, you'll know you can justify the extra cost for expensive hiking boots when you get them.
Packs: Currently, I hike with my old college backpack. If you have one lying around the house, or you know someone you can borrow one from, I'd start with that. Mine has served me well, although I wouldn't mind finding something that distributes the weight a little better.
Hydration stuff: I have insulated bottle covers with shoulder straps and I don't want to use anything else! They are a good alternative to hydration packs for a number of reasons. One: you can get them just about anywhere for a few dollars vs the $30 or more you'll spend on a Camelback. Two: Because they go over my shoulder and rest on my hip, the weight of that water isn't in my pack and it makes my load lighter. Three, and what I think is most important: it's very easy for me to check and see how much water I've been drinking. When I'm more experienced, I think I'll know instinctively if I'm drinking enough water. But, now, i feel I need to watch it very closely.
Another lady I hike with suggested that I could convert my backpack into a hydration pack if I bought a Platypus bladder. She says these are about $10. If your pack has two zippers, you can run the drinking tube out between them without having to cut a hole in it. That sounds like a pretty good alternative, too.
I like to shop at Popular. They have a good range of stuff from economical to reasonable quality. REI is a great store and a lot of fun to shop at, but they are top quality and you pay for it. I haven't found a Popular close to Avondale, but if you ever want to go shopping, maybe we could meet and go together!
Hope this is helpful!
