Yes, I'd contact my 6x9 negatives if I were in your situation.

I often reduce my 4x5 negatives. So small prints are a good idea.

When you get back, you'll have plenty time to find a suitable enlarger.

I'd look around a few threads for advice on that front. While I'm perfectly happy with the Omega DII, I know plenty people are much happier with dichroic color head enlargers, because then you get the advantage of diffuse light source and not have to mess with filters for multigrade printing.

p.s. I've got 2 rolls of TMY-2 with 6x9 shots washing right now...
