Mike,
Welcome to hiking! Good choice for a hobby and I'm glad to see your wife is going to join you. You picked the right web site to get information. You'll find plenty of help here, I certainly have in my 6 months as a member.
Sorry, I can't help you with any trails in your area, I'm not familiar with that territory. As for gear and clothing I'd recommend
Eastern Mountain Sports and no I don't work for them. Though there gear is pricey, it'll last you for years as well as keep you safe and comfortable on trails. I find the staff at the EMS stores I've been to is just as passionate about hiking as I am, therefore they are helpful and I'm sure can answer your questions.
You sound like you are brand new to this; we all were at one time. I'll just throw a few suggestions at you for what to have when starting.
Hiking boots, very important, get a pair of GOR-TEX boots and I'd also say look for a pair with good ankle support.
Backpack, since you'll be doing daytrips start out with a backpack that is sizeable for just a daytrip, something to store your water bottles, food, accessories etc.
Compass and GPS, I love my GPS but I can't always get a fix on enough satellites, plus like all high tech items it can crap out. A good land navigation compass can be purchased for as little as $10.00 and is suitable for a day hike.
Topo maps... VERY IMPORTANT, have a topo map of the area you are hiking in and try to get any kind of a map of the specific trail you'll be on. Lastly, use the internet to get trail info. There is a ton of data out there on hiking trails, take advantage of it, print it out, bring it with you.
Hope this helps, enjoy your new hobby. Try to hit the WMNF for some hiking if you can. You'll find quality trails for all levels of hikers. That is the beauty of it!
