Cal kit questions --looking for advice and insight

I am trying to create a TRL cal kit for a customized substrate. The bandwidth I am interested is from 10 to 60GHz. Anyone can share knowledge on how I can come up with a cal kit for this purpose?
How do I decide on the TRL dimensions? Should I avoid frequencies for which the length of the cal kit may be 1/4 or 1/2 wavelength? Any other considerations?
How to come up (or extract) with parameters for this kits for VNA use?
How is the reference plane decided?
If I am trying to measure a circuit from 1GHz to 80GHz, for example, do I need several different kits to cover the full band?
Thank you!
