Using the method I listed above and your max bench, I would do this
135x5, rest,155x4 rest, 185x3, rest, 205x2, rest, 215 as many times as you can then strip the weight down to 135 and immediately rep out as many as you can. On the last set, when you can do 30reps with the 135, you should be ready to easily do 225. If you do this let me know when you can do 225x5.
The advice above is great. Deadlifts and squats will help you in your lifts.
