This is a crappy answer, but ... as long as it takes! The LSAT is the single most important part of your application. Look at the schools you want to go to. What is their median LSAT? You need to aim higher than that. Then, prep as long as it takes you to get to that score. Or settle for a lower ranked school.
I'd say from where you're starting, you need about 6 months. But that's just a guess. I'd say two hours a day M-Th of reading how to work problems and then doing problems and going over the mistakes. Then a preptest or two every weekend, being sure to GO OVER THE ANSWERS. Going over the answers is where you will be improvement. If you don't go over them, you'll never get better. Take one day off during the week and every other week do a preptest on BOTH Sat and Sun, other weeks just do one. Increase your times as it gets closer to test time.
If the Kaplan system isn't working for you, you could try buying and reading the Powerscore Logic Games and Logical Reasoning Bibles. However, I generally wouldn't suggest mixing systems. You need to pick one way to work your problems and do it that way every time, lest you get yourself confused during the real test.
These are all just *my* suggestions, however. Other people might tell you different things.
