Will these themes work on Blur-based ROMs (DarkSide, Aura, NottachTrix, etc.)?
No. They are designed specifically for the T-Mobile Theme Engine that is integrated into CyanogenMod 7. They will not work on Blur-based ROMs, as they do not incorporate the Theme Engine. Any CM7-based ROM for the Atrix 4G (such as RedPill-CM7 and CM7 itself) can use these themes, provided the ROM also includes the Theme Chooser app (some CM7-based ROMs, such as Neutrino, do not include it by default).
Will these themes work on CM9 or other ICS-based ROMs?
Not at this time, as neither pure ICS ROMs nor CM9 include the T-Mobile Theme Engine. In any event, I don't have CM9 or ICS on my phone, thus I couldn't test it even if they did.
Will these themes work on CM7-equipped phones other than the Atrix 4G?
They should, as Theme Chooser themes are supposed to be compatible across multiple devices, but I do not guarantee this. Additionally, these themes include elements that are specific to the Atrix 4G (such as "H+" data icons) and do not include lower-resolution elements (MDPI and LDPI); the latter means that the theme won't work on some phones, while the former may make your phone look a bit weird.
Could you tell us your inspiration behind the names of the themes?
Alien Green - A common color to represent aliens in science fiction
Cool Blue - Think of the blue of a mountain lake or the deep ocean
Dark Side Red - The Star Wars
films, as well as nottach's DarkSide ROM
Deep Purple - "Smoke on the Water" and "Hush" are great rock songs
Grid Orange - The TRON
and TRON: Legacy
Ice Blue - Just a lighter shade of blue, reminiscent of ICS
Mellow Yellow - The trippy Donovan song from 1967
RedPill - The Matrix
films, where green is used to represent the Matrix
Why am I not seeing the 1% battery icons?
Go into Settings - CyanogenMod Settings - Interface - Status Bar Tweaks - Battery Status Style
, and make sure that it is set to "Icon (Default)."

Note that most of these apps were already themed in UpwardSpiral's original themes; additional ones were added by me. Most apps just have themed launcher icons, while some apps have additional themed elements. Finally, I may have missed a few, since some of the theme configuration files were hard to decipher in order to nail down the specific apps.
Could you theme "application X"?
If I can, I will, but it may not happen immediately (and if it's a paid app, there's probably very little chance I will, especially if it's an app I'm not interested in purchasing). All of the themed apps in the above list were either already themed by UpwardSpiral or were apps I already had which I themed myself. If you suggest a free app, I can install it and try to theme it (even if it's just to add a themed launcher icon), but I make no promises.
Are there apps that you have been (or are) unable to theme?
Several, in fact. This mainly has to do with the limitations of creating Theme Chooser themes under Windows: the tools being used do not allow for upper case characters in filenames. Annoying, but since I didn't write the tools, there's little I can do about it. The following apps are ones that I have been unable to theme:
Alarm Clock Plus
Camera ZOOM FX
There are undoubtedly others out there that I will run into myself, or will be suggested by others. Believe me, I'd like to theme them, but unfortunately, I can't.
