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.
Right. 42t in the middle.
Yeah, 26t is low. I'd like to use a 24t, but I've done a 42t to a 24t jump on a 46/42/24 half step with friction shift up front. It's a doozy and I don't think it would index well. Some of the hills around here are just ginormously steep and sometimes long to climb. Most hills, though, I can easily pull with a 36t middle ring and 28t low cog. A really low "bale out" is nice because there's a lot of hills overall. It can be taxing after a 20+ mile ride. And, sometimes I'm just not up for it without a sufficient low.
