Hey everyone. First time poster here!

I travel frequently for both work and leisure, but unfortunately, was always ignorant of earning MQMs and miles in general. For example, in 2011, I had 24 MQM segments on Delta and never realized how close Silver was. Long story short, I want to change everything in 2012, and learn the ropes of traveling wise. This starts next week :

I am traveling from New York to LA on Thurs, Jan 12, returning Mon, Jan 16. Only necessities are flying Delta, using a NYC airport, and being at work on Tues morning, Jan 17. I would also like to keep costs affordable - I understand flying first or business yields more miles, but the difference in costs from economy lowest & discount from even economy flexible is a sizable difference.

Again, forgive my ignorance - do volunteering to be bumped and sdc's add miles, or just provide other perks (like travel vouchers)?

I would appreciate any guidance / advice more experienced Delta travelers can offer, and fast! Trip is in 8 days! Thanks in advance!
