How many miles [:?]

Good afternoon all
Am I correct in thinking that the following will apply, I’ll shortly be booking the following flights and wanted to know if my assumptions is correct.
LHR to SFO = 10,716 FC Miles (round trip)
In between the above I will also be doing SFO to HNL, this for me is where it gets a little complicated, it states on the Hawaiian Airlines web site that the reward for this flight is 2,500 Airmiles (I think) so this would total 5,000 miles.
Total miles earned for the complete trip 15,716 [:?]
Is the above correct and if so, can I book the complete trip direct VA and will I automatically get all the miles or do I have to register with Hawaiian Airlines to qualify for their part of the deal. Finally, what is the difference between, ECONOMY (M,Q,V,X,N*) and ECONOMY (Y,B,L), you earn 25% more miles with the Y, B, L, for the LHR To SFO legs.
I hope I have explained myself adequately and thanks in advance for any replies.
Cheers [y]
