First: Take all the excess CRAP off yer bike.
If you want to use what you can, it will take some doing. with the origional wheel, remove the freewheel and reorganize the axle spacers so as to get the chainline right with a single rear cog. than redish the wheel to re-center it with the new axle spacing. I had to grind the excess spoke tips sticking through the niupples into the inner tube ((the non drive side spokes were a tad long, you could also replace them with shorter spokes if you don't like using a drumel tool). Once the rear wheel is set up, the rest is a breeze. take of one of the chainrings. My Dawes came with a Strong Light crankset, and the original chainring bolts were short enough to be used as a SS. The BB was a good size as well. Every thing really lined up perfectly for me.
I'd be happier with a newer hub and tougher rim, but I'm pretty impressed with the origional wheelset so far. To do so would require you to spread the rear triangle a bit to accomodate the wider hub spacing. I will eventually do this to mine.
