If you have the financial and mental resources to get a degree, then by all means get one. At the worst you're going to have pay $$$ for student loans. At the best you've gained some valuable knowledge and skills that will allow you entry into huge corporations that offer interesting work and fat 401K plans.
Actually being successful in CompSci endeavors only partially depends upon a degree. A degree will help you get some attention when promotions and raises are being considered, but enthusiasm, dedication, personality, responsibility, initiative and experience are are going to get you even more (except with the most PH of PHBs).
Having a BS degree can only help you in a career as a developer/programmer/engineer/geek. Lack of a degree is just going to make it harder, though hardly impossible.
