There's a tip in that book that made more of a difference to me than anything else I've ever read on time management. If something will take less than two minutes, just do it. Don't worry about its priority. It'll take longer to put it into a system designed to remind you later than it will take to just get it done.
That one revolutionised things for me. You make a huge amount of progress immediately.

Vin,
That sounds like this book:
Do it Now: Break the Procrastination Habit Which I read a few years back, and it was pretty good too.
As for filing, just start some files and keep 'em in date order. Keep all your payment receipts in one file, in date order. Keep your accounts up-to-date regularly. Use a diary (I like a paper one) and a big year planner. If you have bits of paper you don't know whether to file or chuck out, stick them in a big envelope - one for each month - and just file the envelope at the end of the month; that way you know for sure that you'll never chuck out a bit of paper you may need at some later date.
And the one thing I think is a must, a Things To Do List. Don't try and remember things, write 'em down. And spend five-to-ten minutes at the end of the week to plan your next week, and spend five-to-ten minutes at the start of each day to plan your day. It saves running round like a headless chicken.
I also know how to be extremely organised, but often I'm not!
