Advice for new MICRO HD

I opted to cease my suffering and bought a MicroHD which will be delivered today.
Would appreciate some advice on the following:

1- Should I update the firmware via g19 or USB, or is there no difference ?
2- Set the LNB to 10750 ? Am going to be using the SP1LL LNB
3- Regarding the Sg2100 motor, am assuming it would be best to set it to "reference" then reset it via pinhole on
motor itself before firing up the MicroHD ?
4- For usuals/aiming, my Due South sat used to be 74W (RIP), now its 72W. Would it be best to:
A- At motor to position 0, manually aim it to 72W
B- At position 0, enter my location, then make the motor move to 72W via USUALS ?

By going w/ A, won't USUALS be off by 2 degrees?

5- Signal strenght, whats the max I can expect the Quality to hit? On the S10, it never peaked past 77%.
Same for Micro, or will it go higher, or lower?

Anyone have any other advice, it be appreciated.

Cheers, K
