Regarding hovscorpion12's recommendations:
Pass on FCP - I don't know a single ME that uses that app, and I've been an engineer for 21 years (and know dozens of MEs). Pass on the Firewire adapter - very few peripherals in today's market use FW. Pass on the VGA adapter, unless you're using an old TV for a monitor. Pass on the DVI Adapter and Dual-Link DVI Adapter. Pass on any Epson printer - they use built-in print heads, which are useless when the heads dry out and the printer will need to be replaced; get a good B&W laser printer - I've got a workhorse Samsung laser printer and a cheap Canon inkjet, and use a pro printer for important stuff (your friend will use the lab printers). And, maybe pass on the Gigabit Ethernet Adapter - I have one and need it about 3-4 times a year to connect to a router to troubleshoot it.
I have that same Mac that hovscorpion12 spec'd out, and bought it on Apple's refurb store for $2800 - there, I just reduced the cost about $1300... which buys a lot of beer and ramen.
