Rotors are 183 so I assume I need this?

Never done this before, hence the NOOB mistake

No, not that one; you need this: http://www.ebay.co.uk/itm/281089427645? ... 1423.l2649

However...
...your caliper is a no3 , which is normally used with a 185mm disc on the front. The adapter means you have to go up a size, so you will need a 203mm disc on the front.
fun and games!

And a new disk. Assume my rotor is a standard one and not floating. How can I tell?

TL

That's the one.
I don't think floating discs were invented when minis were around. A plain flat disc of steel type rotor is what you need, but one with a wider contact area than is common today. Minis had very distinctive, quite pretty, wavey discs.
 
Why can't there be one standard!

Also IS mounts seem to work really easily, there is no thread on the frame/fork, but everything seems to be going post mount, is there some better reason for them?

adjustability for starters
 
I will admit I think the IS mount stuff I had were using post mount adapters, so found them easy to adjust, I suppose directly mounting to IS would be not as adjustable... assuming thats what I had, I found mounting those to frame and fork, easier and better than just using post mount... go figure.
