Flying Club Query - what counts as a round trip?

Hi all!
A first post here on V-Flyer and it comes with a few questions.
I have booked a trip to the USA with my other half for this Christmas. We booked via Dialaflight and our flights are:
MAN - ATL - 23rd December in Upper (Z) - VS109
ATL - San Antonio - 23rd December in Business (Z) - VS5259
San Antonio - JFK - 5th January in Economy (X) - DL1274
JFK - MAN - 7th January in Economy (N) - VS4022
Being new to Flying Club I have created an account for myself first then referred my other half. I was wondering whether this referral will earn me bonus miles as I am unsure if this trip is classed as a round trip? If so, would the Upper Class bonus apply or the Economy bonus?
On another note, I noticed on 'My Booking' under Flying Club it stated that each flyer would only get 6,135 miles and 5 tier points for this booking. Surely this is incorrect as all our flights are eligible for miles and TP's? I also understand that following the changes to FC I should now earn more than the 6,135 per person as the best rate out of the old and incoming new system will be applied to each individual flight?
And lastly, once we have completed all of our above flights I was thinking I could benefit from the 20,000 miles needed now for an economy return for one person but this would only be possible if I could pool both mile pots together. Is this easily done?
My one concern is that flying out UC and back Economy means a rather depressing return journey home!
Any help is greatly appreciated and apologies for my first post being so full of questions!
Thanks
