I think U probably can still build on what U have b4 going the hardware way...
stuff like proper monitors, room treatment, LEGAL SOFTWARE, maybe a UAD-1 or a Powercore, Proper controler...

On my view if u don't know what u need 2 buy then u don't need it...

Concentrate on exploring what I have 2 the fullest.. choose only 4-5 VST is and FX/ Sequencer.. MAKE some bloody noise... In time U'll know if u really need anything else and what!

my 2 cents,
