>Would it make much of a difference if I used a0 instead of d0?

depends on what you want to do... for example, you can't use
math/logical instructions like muls/and/or/not with address
registers..
and vice versa .. you can't really use d0 as a proper address
register... but if you just want to store the value from d0 in a0
(in order to get some free registers) then i see no problem..
