Just install the GTK2 and Emerald themes, activate them, and you're good to go. If you're not using Nautilus-Elementary, you can deactivate the Nautilus-Elementary-specific theming by commenting out the "include nautilus-elementary.rc" in the last line of the gtkrc.
Note, Emerald doesn't work in Ubuntu 11.04 by default, so if you're running that or any Ubuntu 11.04 derivatives (like Mint 11), you will have to get around that, by compiling Emerald from source, or something like that. A quick intenet search for "Emerald on Natty" should help you fix that.
The recommended icon theme is the default Mint 11 icon theme, which is based on Faenza-Dark (I think)
Known bugs:
-Some of the text colours aren't the same in all applications and all circumstances, but I have done my best to make things consistent.
-The bottom of the Emerald theme seems to snap 1 pixel below where it's supposed to
-Firefox and Thunderbird (and LibreOffice/OpenOffice, for that matter) don't support GTK theming very well, and the text colours, for example, may not (will not

-the menus, if they don't have any icons, can start before the vertical line, which shouldn't happen
This comes with the Emerald and the GTK2, so you don't need to download them twice.

Gorgeous, love the greens and thought I'd suggest you check out this: http://gnome-look.org/content/show.php/Murrina+HTC+Android?content=128878 did it perhaps influence you? I'd love to see something with the best of the two done up. The metacity theme ive chosen is Green and yours is making me second guess myself, i cant for the life of me remember where i found this so let me know if you need it: http://i.imgur.com/p9RW1.png
Thanks :) Yeah, that looks nice. But it didn't influence me, mine is a straight port of Skillet98's Windowblinds skin "X360A" (http://skillet98.deviantart.com/art/X360A-Dark-167127513) But, yes, the style is similar, and they're both nice :) As for the Metacity theme, it's nice, too, but mine is Emerald, so the glow and fancier effects.
Looks nice and minty :)
Thanks! It's not really meant to be a Mint theme, but I guess the green matches the Mint style pretty well. :)
