Cheapest Way to Vegas in PE

Hi,
Wonder if someone can offer any other options for the cheapest way of making a trip to Las Vegas next September with my wife in PE. We went this year and paid approx £840 each, fare code K – we booked during the sale.
I have the MBNA Black VS CC, which I transferred to from the Mastercard in July.
I’ve currently got just over 100000 points. By early January, which is when I was thinking of booking (Sale time again hopefully), I’ll probably have about 110 – 115000.
My wife has 23000 points.
I’ve got one companion ‘voucher’ (at least that’s what it says on my Flying Club statement)
If I’ve understood the T&Cs correctly, I should be entitled to one PE upgrade voucher at the end of the (calendar) year. I haven’t checked my spend exactly since moving to the black card, but I’m sure I won’t have spent £10,000 which would give me the 2 upgrade vouchers. And that begs another question – are the PE u/g vouchers redeemable against normal miles rewards bookings or not – I’ve seen conflicting reports. Would the ideal, i.e. cheapest, scenario be 100000 points and two PE u/g vouchers?
Options – not sure whether some of these are allowable under the T&Cs:
2* Economy rewards (100000 points) and pay to upgrade?
2* Economy rewards (100000 points) and 1* u/g voucher and 1* pay to upgrade?
1* W or S fare and companion ticket? Typical Price?
1*K fare and 1*economy reward + u/g voucher
Spend more on the c/c to earn 2nd u/g voucher
Spend more on the c/c & buy miles to get 150,000 miles (2* PE reward)
Other options ?
TIA
Ian
