Good Morning, Daniel,
There should be no rush to use the film. Frozen Tech Pan will be good for years. I don't know if freezing the Technidol is a good idea or not, but there are similar developers available if that doesn't work out. Shot and processed properly, Tech Pan in 120 will easily challenge 4 x 5 print quality, but that assumes top-flight lenses, tripod use, a reasonable highlight/shadow range, etc.
