Before you get bent out of shape, just know that the average 19 y/o doesn't BUY $4000 in recording sofware. This is not a slight on you specifically, just that it's so uncommon that its a little difficult to believe. Over the years we've had a lot of "klidz" pass through here with "warez" and "appz" and such. This is not to imply that we think you are a liar, not at all. All I'm saying is that it's uncommon. Nothing more, nothing less. If you've paid for all your software, good for you, that's the ethical thing to do and there is no reason to defend yourself any further.
As I said before, at 19-20 I had a lot of gear also... I went to school full time, worked full time, and did competition-class car audio installations on weekends, 12-14 hours a day. This provided for a lot of recording gear that I had very little time to use
.
Anyway, that said. lets move to your question. What do you need. That really is a question you need to answer for yourself, because each of us come from different backgrounds and aspects of the recording world. I, and more of a midi composer, mix mastering kinda guy, so my recommendations would fall along the lines of synth modules, Sonar, TC finalizing products, etc. Others might have other recommendations.
What do you actually record... friend's bands, your band, do you compose and record rock, metal, country, techno, do you create dance mixes of covers or original material? If you ask yourself these questions, you'll better able answer your big question - what else do you need.
Need is a funny word too... I've seen "darn good" recordings with significantly less stuff than you and I have... and horrible recordings on "fantasy gear" that the common man can only sniff magazine ads to see.
A few years back I would brought into the final stages of a project, primarily to finalize and master their recordings, to put together a glass master. Unfortunately, the material they gave me was impossible to work with, so we booked more time in the studio they had rented to rework some of the tracks. Essentially, their near-fatal mistake was not to use the house engineer of that studio, but rather bring in a "friend" who claimed to be a recording engineer, who in my opinion didn't know which way to face a microphone. But that's another story. After going through all their settings in the console, it was quickly determined why everything sounded so bad - the "ingunear" had created several loops, from direct outs of various channels, to one of the busses, phased backwards, with weird EQ settings to compensate for the out of phase, audio loops. So, essentially this band wasted nearly a week of time in front of an amazing console, the Sony Oxford, just to have their recordings sound like a rock band yelling through digital kazoos. Yes, we had to record pretty much everything over. At least the drums were recorded correctly.
So the moral of the story is... its not necessarilly what you have, but how well you know how to use it. I'm not saying you shouldn't buy "hot gear", just saying often, such items are purchased more of out desire than actual need. And as you've discovered already, gear (and software) isn't cheap.
Imagine what 5 days in front of an Oxford cost this band... to get fancy kazoo sounds. Then imagine what it cost to do everything over in three days, plus my bill on top of that
I guess internet recipients don't deserve English. I'll reserve my help for those that DO want to communicate in English. And that DO have enough respect for people who ANSWER their questions, that they will TAKE the time to type CLEARLY and who DO understand that THE FUCKING WORLD DOESN"T BELONG TO THEM EVEN THOUGH THEY ARE SPOILED LITTLE BRATS
