Should I bother doing a used oil analysis on it or just wait?
Don't bother. You won't get any usefull data from it other than casting sand and break in metals showing up(I think it's a waste of money this early) Personally I would wait until you hare broken in and have a steady diet of a quality motor oil(looks like it's M-1 for you) in it for at least 10K miles before I began to do a used oil analysis.
Since you have chosen M-1 I would run it For 2 5k mile intervals then do a used oil analysis to establish a base line as well as to evaluate the motors health.Sounds like you have a good break in regimen planned.
Congrats on the new Tacoma. The new motors seem nice.
A used oil analysis might be of interest to the group as to what Toyota puts in those engines at the factory. Otherwise you are not going to get any useful info.
