Thanks, guys. No, not an astrophysicist. Just a guy who's very interested in stuff like this.
A couple of things:
Everything in Back to the Future would be impossible except we forget Einstein's Coolness Principle: if the subject matter is cool enough, Marty McFly can do whatever the **** he wants. Bill and Ted, Dr. Who, and the Terminators, I beleve, all work under this principle as well.
Going back to 1984 and buying a whole bunch of Transformers would probably be easy. Just go to a coin show, buy a whole bunch of era bills and coins, and you're set for currency in 1984. You can't rely on credit back then because, aside from your credit card not working, retailers would probably wonder why you have a credit card with an expiry date like 03/12. But no one's going to be wondering where you got this money as long as it doesn't go in electronically: buying a bunch of stuff from a retailer isn't going to draw attention unless it's an exorbitant amount, so just shop around. No one's watching the video cameras and, even if they got your identity, they'd think someone made an error because, hey, a kid couldn't possibly be buying all this stuff so that adult buyer isn't who we think he is. So future you would have no problem except a cool story to tell about how somebody assumed his identity for a day.
And, to stay on topic, check out the Lorentz Contraction on Google. It's the third screwball effect--along with mass dilation and time dilation--when dealing with lightspeed.
