Input levels into the mixer

I would tell you not to use the XLR's on the amp,put a SM57 in front of it.
I like miked amps.

I like miked amps too but I suspect you've never used the DI on a Tech21 amp. You can put a '57 in front of the speaker if you like but it'll sound about the same and it's just one more thing to trip over on a crowded stage. The internal DI box is speaker and mic emulated. The only problem I've ever had is that the connector isn't exactly top notch and some XLRs are a bad fit.

A pad somewhere is a very sensible suggestion.

You are completely correct.I have not used a tech21 amp or DI.
My bass player uses one of their floor units and it seems pretty well made.
