ok you essentially need
a computer
an audio interface (with pre's preferably)
some monitors (speakers)
a mic and optional stand
a D.A.S (digital audio sequencer)
i want get into acoustic sound treatment at this level yet but this is something you will have to address in the future if you keep at it
and of coarse the appropriate cables but that depends on what set up you buy so i suggest you tackle the items i mentioned first
just tick the items you have and focus on what you dont, what computer have you got. i also think people are suggesting reaper because its a good program and cheap. it can do almost all what the more expensive programs do too
