Dennis,
Your price is definitely too high (unless it includes sales tax - we don't have sales tax for farm use in TX). I'd be looking to get your dealer to sharpen his pencil some. Offer him $1,500 or more less. If you take the offensive and tell him what price you are willing to pay, you might be surprised. Be sure and tell him you consulted this board. He will know you can't be BS'd.
On your second question...a remote hookup is a set of quick-connect hydraulic hoses and a control valve mounted like the valve for the hydraulic lift. On most compacts, you can have up to three. This allows you to attach an implement which uses hydraulics (post drivers, bat-wing mowers, some box blade scarifiers, log splitters, etc.) Many folks are using one remote for a hydraulic cylinder which replaces the toplink or tilt for the hydraulic lift. You can always add one of these when you need it, but sometimes it is best to bargain with the dealer at the time of purchase. If he stands to make a tractor sale based on giving you the remote valve at cost, he just might do it.
Good luck,
JimI
