Hi,
Paul will have to answer what's supposed to be in the kits and/or if something has changed or if there's been a mistake.
If you indeed have 300ohm resistors instead of 470ohm you can use them for R2, R6 and R7, R43 and R44 without any problems.
I'm 99% sure that you won't have any problems using them for R8 and R9 as well. It will put a bit more strain on whatever is driving the step and direction inputs but I'm pretty sure it'll work just fine. Atleast you shouldn't be able to damage anything by trying.
As for the TLP127 you can get them from DigiKey in single quantites, part number TLP127FCT-ND, the LTV-815S and LTV-355T should work as well.
