I take on board what you say about mounting the capacitors close to the chip but please could you tell me what TYPE of capacitor I need. It doesn't show them as electrolytic, so what type would you recommend that I order. Sorry to be so dim.

The 1uF's should be film caps (greencaps) - polyester is fine for this application.

If you wanted to get it going in a hurry, Tantalum's would work fine too, but not quite as well.

Agreed on the film caps but I would try to stay away from tantalums. They don't often fail but when they do, the magic smoke comes out - sometimes quite violently.

Indeed - I sorta forgot to add my "for prototype purposes only" disclaimer. I'd never use a tantalum in something I wanted to keep.
