Taig cnc ready help for a newbie

Hello guys. I am new to the cnc milling scene and have been doing
lots of reading the last couple of weeks and need some help to setup
a Taig cnc ready mill.

Can someone please recommend a good setup for a Taig. I will mostly
be dealing with Aluminum metals. I need a setup that can work with
metals for long periods of times!!!

----Setup i am thinking about----

MILL...Taig CNC ready mill 2019CR

SOFTWARE....I would like to run a XP Windows based software if posible
(guessing Mach 2).

DRIVER BOARD... XYLOTEX Three Axis Stepper Motor Drive

STEPPER MOTOR....???? Need help here. I am guessing something with
200-300oz

SPINDLE MOTOR.....???? Need help here. Is the one that comes with the
Taig good or can it be upgraded to something with a more powerfull
motor for working with metals?

POWER SUPPLY....??? Need help here.

All comments are welcome
Thanks in advance guys for your help
