Pavel's PTP (Power to the People) routine worked wonders for my basic lifts. Added 80lbs to my dl and 50lbs to bp in about 5 months. You can throw squats in also.
Do 2X5 of each exercise 5X week. dl, bp + squats. Nothing else (actualy may be better to do 2 separate cycles--DL + BP, then SQ + BP) Don't do any other lifting. First set 80% 1RM, second set a bit less. Start off real light. If you can do 100 10X then start with 90 for 5 reps. It will be easy for the first 5-10 workouts then will get harder. Keep adding weight each workout. Do not go to failure. Don't throw in extra weight/exercises in the beginning. You'll leave the gym with energy but that's ok. By the end of the cycle may have to do singles--especialy with dls. Weights will go up quickly. Also, might only be able to handle 3 workouts per week near the end of the cycle. At that point start a new cycle---begin real light again, etc.
Best of luck
