You don't have to buy ANYTHING, what you have will work fine.
I guess you will be mounting the 42 in the middle position so that it is adjacent to the 26. Try it, if it doesn't work, go with 42/32. 26 is very low.
The FD that you have will work fine. You will be adjusting the stops so that it only accesses two of the rings.
