Cheers guys, I have read the stickies several times and get more confused everytime I read the one on honing. I guess it's a case of taking the plunge and moving on from there.
Obviously not practicing on my favourite razors.
The main decision is between natural and synthetic stones - the issue is that, maybe with the exception of Coticules, no stone can be used for a whole progression from bevel setting to final polish. Natural stones have their own unknown vagaries in terms of where they sit in a progression i.e. one coticule may differ enormously from another. Bevause of this, its advisable to use synthetics becaues, even though they may not be directly comparable between brands, you know that a 1k Naniwa will duffer from a 3k etc. Using synthetic stones lets you know exactly where you should be so that if you have a problem you can discuss it with spmeone who has the same stone.
If you want a stone for touching up a blade then the 12k Naniwa is a good starting point. There are cheaper alternatives including a range of natural stones (Welsh Slate etc.) - however as a beginner you will have no idea as to what the stone is doing whereas with a synthetic, the stone will show you how much steel is being removed.

Short for Japanese natural stone.
C'mon Rob, give us a Jnat primer please (Neil doesn't really cover this in the sticky)!
The only information I can give relates to my own set up which is a Nakayama stone with 3 slurry stones (naguras) and a finishing slurry stone (tomonagura).
A japanese stone can be used for a honing progression after bevel setting by using different grades of slurry stone beginning with soft and then through to the tomonagura which is as hard as the hone itself. The principle is that the softest stone breaks down into a slurry and begins polishing the bevel leaving a haze rather than shine. Working up the nagura stones improves the polishing effect and helps to erase the scratch marks left at the previous level, just as a progression frpm say 3k, 5k. 10k does on synthetics.
The final slurry stone (tomonagura) needs to be about the same hardness as the hone itself and is used to bring the haze to something of a mirror polish. Opinions then differ as to whether finishing on the stone with plain water adds further.
I'm no expert in these stones but I can say that the edge they leave is very smooth - you can see the difference in the edge using a loupe. They are a bit more effort than using synthetics but worth it.
