end ratio and new tyres

hey all
just wondering if anyone knows how readily available 4.4 ring and pinons are and how that will effect things as a percentage at the wheels? im looking at changing to a different size tyre/wheel and its going to be like a 7.6% change in Dia at the tyre. through my calcs going from a 4.1 to a 4.4 will be about a 7.3% change in end ratio so that should pretty much even things out right?
4.4-4.1= .3 (so thats the amount of change)
100(.3/4.1)=7.3 (thats how much of a change in a percentage over the old)
guess what im sayin is the 7.6 change at the tyre the same as a 7.6 change made at the ring gear..? should be i guess..
looking at going to a 17 inch rim with thoughts of better brakes but all just thoughts at the moment. most brake upgrades wont fit under 15s i also wanted to go a little wider than current 205. would like to go 16 but there dosnt seem to be alot of tyre choice around that size 225/45R17 seem to be rather common within competition tyres.
