If you're not a mechanic, probably the handiest thing you can pick up is the idiot book, just enter "How to Keep your Volkswagen Alive" into any book site and you will find it.
Muir isn't the be-all-end-all of vw maintenence but the proceedures and symptom-identifying features of the book are without equal. He tends to err on the side of caution but it will keep your car running.
If the rest of the vehicle is in as good condition as those pictures claim, you probably won't need much. Little more than a couple extra quarts of oil and an extra fan belt.
If you do get the Muir book I mentioned above, he has a section devoted to tools you should have on hand for various uses of your bug. He suggests (I have all this stuff on hand because my car isn't in nearly as pristine a shape as yours ;) stuff like spark plugs, full rebuild kit for the distributor, bulbs, fuses, and an array of gaskets.
