UNIX for Dummies Questions & Answers

Hi,
I'm looking to go into a career related to either Unix, or web development(or something alike). I want to get a Bachelor Of Computer Science degree(I'm planning to). I don't know which kind of jobs might be a good choice for me though. Like I said, I'd like something to do with either Unix or Web development or similar, but as far as a salary range, I'm fine with a starting salary $40k or over, but I'd like to be able to be making approx $120k(give or take a little) after about 10 yrs. Can someone please give me some info / job titles I could look up that would fit what I'm looking for? I really want to do something Unix related but I love working with computers(diagnosing problems, fixing them...software or hardware related) so pretty much anything computer related I would probably like. If someone could give me some ideas of things I might be interested in I'd really appreciate it!

systems engineer, unix systems engineer, network systems engineer, virtual computing system engineer, event processing systems engineer.....

... you get the idea.

Thanks... could I become a unix systems engineer or network engineer right off or would I have to start with something else? If I would have to start with a different job to be able to get that job, could I get the job after 9 - 10 yrs of doing a prior job?
Thanks
