Richard, you've finally seen the light!!!
As far as the parts you mention: the front axle and driveshaft is the same, brake booster is a fairly simple swap, headers/manifolds go with the motor anyway due to 2 extra cylinders, trans cooler is extremely easy to adapt the lines, and the tranny will require a modified rear driveshaft and possibly a modified support crossmember. If you can't handle these minor issues, you have no business even attempting this swap. The wiring will be far more time and labor intensive than any of this stuff.
My take on the cost is this:
$1000-2000 - donor vehicle
$100-200 - modified driveshaft
$0-100 - crossmember modification
$0-200 - exhaust modified to fit
$100-500 - misc. odds and ends, fluids, gaskets
Total cost $1200-3000 for someone who can do the work themselves and source good parts. This is probably the absolute minimum for a stock swap, obviously any bolt-ons or rebuilding will add to the cost. $500 for the headers, $80 for the intake spacer, $200 for roller rockers and $400 for a cam and valve springs will do wonders for the motor though, if the budget allows.
