Okay let me just start from the start. My cold diagnostic was a 145 (June 2007). Since then I've studied for about a month and a half taking a PT scoring a 149 (December 2012) and a PT today scoring a 155 (PrepTest A from SuperPrep). I've seen improvements in just about every category except assumption questions in which I've scored in order of PrepTests, 0/3 (0%), 2/3 (66% guessed correct answers), and 1/5 (20%). I've been through the Logical Reasoning Bible and my assumption question scores still just aren't there; any tips on improving them? Also a peculiar thing is that my flaw in the reasoning questions went from a 6/8 (75%) on PT2 to a 2/7 (28%) on PT3. Are these drastic fluctuations normal especially to begin with considering I'm only on my third PT?

Not sure which type of assumption questions you're talking about though it looks like it doesn't matter given that your scores are generally evidence of a lack of understanding of the dynamics of the test.
My advice is to grab a 7Sage package if you can, or a copy of The LSAT Trainer, and then start fresh and don't take any PTs until you have really developed a healthy understanding of what you're being tested on.
Good luck and feel free to ask us anything!
I agree with everyone here that the LSAT Trainer is a great resource for logical reasoning. For me, the way I remembered how to look at assumption questions was:
Necessary Assumption: What must be true if the information in the stimulus is true? You can test the answers with the negation test (if you negate an answer choice and it contradicts the argument, then it is a necessary/required assumption)
Sufficient Assumption: What must be true in order for the argument in the stimulus to be valid? The correct answer, if added as a premise to the argument, will make it logically valid.
To be honest though, I didn't know the difference between sufficient and necessary assumption questions until I read the LSAT Trainer. I highly recommend working through it, especially for understanding the different challenges that each question type presents.
