I was lucky enough to get a fellowship from my company when I first graduated. I had some intern/co-op experience and waited a year before getting into a Master's program. Most companies have a reimbursement program for advanced degree course work. You may not have enough experience to really determine which path you should be on for a good future. Best to take a year working and decide if you really want to do what you are already doing even more or if there are changes you want to make in that path.
I bought Slackware at the local computer store and installed it on my machine. I had to dual boot because the CD-ROM was connected to the sound card. However, all my engineering classes used UNIX instead of Windows, so I was happy to start poking around my own system and try to figure out how to make everything (or most everything) work. It was fun.
Hackers are just a migratory lifeform with a tropism for computers.
