Heading to ORD off-season

Hi all,
I'm trying to figure out the most effective way to head to ORD for the bank holiday weekend in April, unfortunately falling outside the VS seasonal service.
Currently the booking system is suggesting LHR-ATL-ORD for outbound and ORD-JFK-LHR for inbound. For the sake of travel time I was hoping I could head Stateside via JFK and return using the same route - but JFK doesn't seem to be an option heading outbound...?
I'd prefer to have a VS leg involved so that I can book in PE (at 6'4" I can deal with DL economy for a couple of hours I imagine). I've never had to get DL involved with my trips so I'm unclear how miles/TPs are awarded - I was under the impression that trips at <3000 with DL would bag me 1 TP for each sector...though the site is stating that I'm only going to get 6 TP for the round trip - are TPs not awarded for domestic or connecting flights?
If anyone has had any dealings with this, I could use some insight as I'm going in a little blind here!
