HeXploiT, personally, I like doing missions with a fleet (soon to start doing WH space with them once I get a few more key skills up). There is a lot of money to be made in the market, and it is not something that takes a lot of time to do, and it is something that continues to generate money even while you are away from the game. In fact, looking at my character in eve gate, I see that I have made 4 million today from sell orders (this is profit, not net). As was previously suggested, there is a decent amount of money in ammo sales. I buy low, transport it a few jumps, and sell high. Right now, I am getting a 50% mark-up on the stuff I am selling.
This is what I am using to fund my main character. Now, I havn't lost any ships (yet), that is only because I have been lucky and had good teachers in the game so far. I came close to losing my BC (armor tanked hurricane) in a lvl 4 mission when the room decided to agro me, but my tank held long enough to kill the tacklers and let me warp out. Warped back as soon as I could since the warp out/back time was plenty for my tank to be repped with my fit.
If there is one thing that I can tell you, it is to not fly anything you can't afford to lose. It makes this much more of a fun game. I have 2 BC's, 3 cruisers, and 8 rifters (a frigate) at my corp staging area. If we are war dec'ed, I will be flying T1 fit rifters, because I can afford to lose them. The only time I would consider going out in the battle crusiers or cruisers is if we have a monster gang with a lot of BS's that would get primaried long before I would in my BC.
