a good laptop / desktop with lots of horsepower, lots of ram, and lots of hard drive
yamaha hs50m speakers - these are the standards over here
DAW of your choice - Logic / Ableton / Cubase , if you can find a friend who can exploit the use of EDU discount, DO IT!!! Edu version are much much cheaper (except for logic, logic is only $200 so just buy it!!)
Native Instruments Komplete 8 - everything you need is here, drums (battery), synths (massive,fm8, absynth) , instruments and samples (kontakt) , crazy addictive puzzle game (lol not really but it feels like it) - Reaktor
A midi keyboard - 37 key would be better than 25 keys for chords , oh and if possible something with knobs/faders for doing those WUB WUB WUB ZZSSSH ZZZSH automation , suggestion : novation nocturn / impulse 49
A few books on the DAW of your choice, i recommend the Power! series (Cubase 6 power! / Logic 9 Power! / Ableton 8 Power!) - read these as it will be REALLY beneficial
and if you want to - a nice audio interface + microphones, if you play instruments it would be a good idea to have this
a nice desk and a nice comfy chair to sit on - THIS IS OFTEN OVERLOOKED!!! you will sit there 20 hours a day and please, get a comfy chair that supports your back, a nice roomy desk to put all your gear and sit nicely, dont worry about acoustics for now, just point the tweeters of the speakers to your ears
lastly… dedication, all these gear wont matter if you dont get into it, so yeah
just my 2 cents
