Welcome to the fire, Newguy Chris. I think you'll learn a lot. Definately try out the search engine as this topic has been covered a number of times.
The biggie is tell someone reliable (or better yet, two someones) where you are going, the route you will take, and when they should call search and rescue if they don't hear from you again.
Other tips:
1. Leave a picture or description of your tent, sleeping bag, pack and clothing with reliable person to help SAR people know what to look for.
2. Leave imprints of your boot/shoe treads with reliable person. Make the imprints by stepping on a sheet of aluminum foil. This will help trackers know which tracks to follow.
3. PLB are worth their wait in gold in backcountry areas.
4. Keep an eye on the weather. Better still, know what the weather is supposed to be before heading out and prepare appropriately. Depending on where you are going, this can mean cancelling the trip.
Gear selection is a function of where you are going. Tell us that and we'll help you decide what to bring (assuming you have an unlimited bank account and the ability to carry 120 lbs of gear

).
