3.8 to 4.6 swap, please help me!

Well heres the deal, im getting ready to swap my v6 auto for a 4.6 t45. i have all of the parts to do it (at least i think) so far i have taken out the interior, removed the auto pedals and got the manual pedals ready to be installed once i run the cable through but im waiting till i drop the motor in trans in to do so, i got the auto shifter and everything removed from the center so i have the hole for the manual shifter. Under the car i have removed all the exhaust, drained the trans pan, and removed the driveshaft. i just need to know how to dissconect the a/c and p/s lines so that i can pull the old motor out and get back to work. anyone who can help me out or point me in the right drirection, i would really appriciate it alot!

thanks,
ryan
