I'm intending to do the same but haven't checked what I've currently got fitted yet.
As I understand it, the problem with going down on the front is that the chain will run closer to the swing arm but if you go up on the back you'll be increasing clearance. As a rule of thumb 1 down on the front is roughly the same as 3 up on back (but I'm happy to be corrected if anyone knows better).
With regards to how far to go, it really depends on what you intend to do on the bike. I mostly use mine for Motogymkhana and a 7 mile commute so I'm happy to go quite a lot way with the change so I'm thinking 2up on the rear and 1 down on the front. If nothing else, I figure I'll win the traffic light GPs
