I strongly recommend using the Tangerine Racing engine jack plate.
http://www.tangerineracing.com/tools.htmThis tool is designed to balance the engine/trans on a standard shop jack and makes quick work of the removal and install. Basically all you need to do is get the car up on jack stands, place the plate under the engine, unhook all the bits as described in the Pelican link, and slowly lower it down. Yes, it's 120 bucks...but the time and frustration saved makes it a no brainer.
The mover dolly method also works...but requires you to use two jacks and is easier with two people. And you need to be really careful that the dolly is in the right position and you've got good control of the jacks or risk doing some damage.
I only wish I bought the tangerine plate a long time ago!
Your first engine drop is a true rite of passage! Good luck with it...and welcome to the club.
