The unboxing part two: the Eclipse plugin
Tried to run Eclipse and got some sort of error about Java missing. Installed the java6 runtime environment and development kit, tried Eclipse again, and it's up and running.
And, boy, is it pretty:
That's some hot, hot welcome screen action right there.
Okay, follow the instructions on the Android install site:
1. Start Eclipse, then select Help > Software Updates > Find and Install....
2. In the dialog that appears, select Search for new features to install and press Next.
3. Press New Remote Site.
4. In the resulting dialog box, enter a name for the remote site (e.g. Android Plugin) and enter this as its URL: https://dl-ssl.google.com/android/eclipse/. Press OK.
5. You should now see the new site added to the search list (and checked). Press Finish.
6. In the subsequent Search Results dialog box, select the checkbox for Android Plugin > Eclipse Integration > Android Development Tools and press Next.
7. Read the license agreement and then select Accept terms of the license agreement, if appropriate. Press Next.
8. Press Finish.
9. The ADT plugin is not signed; you can accept the installation anyway by pressing Install All.
10. Restart Eclipse.
11. After restart, update your Eclipse preferences to point to the SDK root directory ($SDK_ROOT):
1. Select Window > Preferences... to open the Preferences panel. (Mac OS X: Eclipse > Preferences)
2. Select Android from the left panel.
3. For the SDK Location in the main panel, press Browse... and find the SDK root directory.
4. Press Apply, then OK
Seems to be all well and good. Went off without a hitch, except...
After the "Press Apply..." part of step 11 substep 4, I get the following:

Now that's interesting. Grabbing info about "active usage" and "which tools are most popular" is fine, but if I start getting targeted ads in my IDE I'm gonna be pissed.
Coming up next: okay, it's installed, so now what?

I've actually never worked with Eclipse much before. I've installed it a few times, gone in and done some sightseeing and sampling of the locals' daughters, but never considered calling it home even temporarily.
Meanwhile, unpack the .zip. I've set up a folder in my home directory called Android and exrtract the subfolders of the .zip into it.
As the instructions instruct, add $SDK_root/tools to my path toolkit:
export PATH=${PATH}:/home/user/Android/tools/
echo $PATH
/home/user/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin
:/bin:/usr/games:/home/user/Android/tools/
'Kay. Good so far.
Coming up in the unboxing part two: Will Jordan's Eclipse install work? Howabout installing the Eclipse plugin for Android? Stay tuned for the answers to these exciting questions, and more...
