Good advice Homie!
Dead hanging is definitely the way forward. I'm currently hanging a 3/4 inch rung (based on the Metolius small campus rung) fixed at 90 degrees on a rafter in my garage. Been doing it for about ten weeks, at first had to use a finger on the other hand to hang it, but am now already adding weights. I set the weight so I can hang the rung for 5 seconds and number of sets depends on how good I'm feeling on the day, usually about 6 each arm. Definitely the best thing I've ever done to improve my climbing.
Other good and simple training is one arm chin-ups. If you can't do them them add a finger from the orther hand until you can. I've found that I've got better results by not lowering to a fully extended arm, rather keeping the elbow bent slightly. I know purists don't like this, but I've been getting a better work-out by doing it. I do 5 reps (obvioulsy adding more weight as I can do more), and number of sets is the same as above.
Front levers are funny things. I don't know how you build up to them because I found I could do them when I first tried. I reckon the best way is to do stomach-crunches (not sit ups), and weighted leg lifts - Hanging on a bar, weights on your ankles and raise your legs from below you to in front of you (under control obviously). Oh yeah, and your hands go over the top of the bar.
I reckon that's enough information for you to go on with, all cheap and easy, hope it works.
