Linux for Mac people

I've used a Mac for years but i'm getting sick of the software bloat and the closed nature of Apple's operating system. So i'm going to run Linux on my mac instead. So that I feel more at home with linux I intend to document the customistions required to make Gnome and the linux applications behave more like their Mac cousins.

Applications required

Here is a list of applications I need to work under linux, and their current Mac equivilent. Ubuntu - Gnome/GTK,Mac OS X Inkscape,Illustrator Gimpshop,Photoshop Scribus,QuarkXpress Sane,ScanWizard tinyERP,Filemaker Open Office,MS Office MPlayer/VLC,MPlayer/VLC Evolution ?,Mail ,iCal ,Address book Mooedit/gVim(cream),TextMate
