Engineering isn't for everyone either. Lots of calculus, physics, and dynamics courses; but you may love it. Don't let people talk you out of anything. Educate yourself on the facts and make your own educated decisions. I do disagree on the fact that this forum is not a good place to get information about the industry. On the contrary, I think it's a great place to get information on the (usually) not so great sides of this industry.

On to the questions:
1) Depends, aeronautical engineering is not in as great a demand as mechanical, chemical or petroleum. If you maintain a high GPA, get some internships and network, you shouldn't have a problem finding a job.
2) Anywhere where they manufacture, design, repair, or maintain aircraft
3) Some make 80k, some make 40k, again, it depends. Usually engineers make in the 50-60k range to start on average.

My last piece of advice would be not to get too hung up on what you want to do with your life now. Go to college and try out your major for the first couple semesters. Don't like it? No problem....change majors. No aviation degree though.
