Set up a bunch of mics, give any soloists a mic, and make sure to have a good stereo pair set up for overall sound.

With the 16 channel mixer and 1010 you should be able to get everybody.

Does the mixer allow using all eight of the 1010's audio ins?
Does the computer?

Set up stereo pair out front, attend a couple rehearsals to test where they should be. Record, listen, try again.. experiment.

I do not work here, but the benefits are still awesome
