Wheelbuilding / Wheel Building / Wheel build help

I was after the lightest, cheapest wheelset I could find (student on a budget) for mainly summer use, also a bit of racing and going up alps this August. Found these from superstar (http://superstar.tibolts.co.uk/product_info.php?cPath=77&products_id=520) however the hubs are discontinued so started looking around for alternatives at a similar price and weight. I've narrowed it down to this build, I'd welcome any improvements, all weights/prices are for a 20/24h set up.

It's what I call a crap build, suitable to someone who weighs 55 Kg and not very powerful. The Stans are not very stiff and not very strong either ( have to be built at a max 120 KgF tension) and paired with only 24 Revolution spokes will build a snakey rear wheel. This in turn will result in the spokes working loose and breaking... my guess is you can get 500 miles out of them before they start popping
Don't be obsessed about the gram at your age, leave that to mamils with 6 figure salaries.
Swap the Stans for Archetype and the rear spokes for Dt Competition and you'll have a nice set of light wheels
