Geeetech i3 Prusa: GT2560 Board DRV8825 motors

May be a good Idea to direct all questions for new 3D DIYers here(including myself).

The printer I decided on was the GEEEtech i3 B

Has the Mk8 extruder
Upgraded to the GT2560 + DRV8825

Decided to exclude the LCD2004

Got the price to 360
Used a cash back credit card 100 off 500 (80 percent of what you purchase until 500)
Like paying 275.

Been told I would probably want to update my hotend and extruder.

Any ideas/ help on setting up this printer for the first time.

or common issues I will run into..
