Weell - I kinda-sorta have a tutorial - my own experience when making an animated spray from the Meet the Sniper video for m1nn0 - and of course my infamous boobie sprays. ;-)
For the final process you can simply use Shizz' tutorial since importing one frame or several frames makes no difference at all - you should just know that spraypaints have a file size limit of 128KB so you'll be able to squish only like 15-ish frames into it.
Also, disabling mipmaps will reduce the file size (and animated sprays were the reason I mentioned this in Shizz' tutorial - the settings are correct now) and eliminating transparency will too (if you have non square pictures consider adding some frames to them to fill the empty space instead of using transparency).
As for the tools - I think you might pretty much use ANY image editing software and ANY good video viewer/editor that lets you display the video frame by frame.
Personally I'm using the following set of tools:
1.
Paint.NET - a free (but less powerful) Photoshop alternative, very intuitive to use for beginners
2.
Beneton Movie GIF - a freeware animated GIF editor. Believe it or not but you'd be hard pressed to find a better program just for handling animated GIFs (not editing the pictures themselves but creating loops etc.). I use it for making boobie sprays out of animated GIFs. ^^
3.
Media Player Classic: Homecinema - an improved version of Media Player Classic - one of two movie players you'll ever need (besides VLC) - it allows you to e.g. advance frame-by-frame in a video and make screenshot galleries of videos which is useful for posting porn on the net with a preview... Uhm...
4.
Blaze Media Pro - a commercial piece of crappy bloatware BUT literally the only program on the internet (in the "likely to have some cracks/serials posted somewhere" category ;-) that could rip the Meet the Sniper movie frame-by-frame automatically
5.
Freecommander - a free orthodox file manager (like Norton Commander, so to speak) I use sometimes, especially when handling batches of files in two directories - trust me, you'll want this one for copying/renaming your frames and a quick and easy overview of both your source and target directory
6.
VTFEdit - *duh*, the program used to create the textures as explained in Shizz' tutorial
Now - just take a video and either rip it with Blaze Media Pro (take a longer segment and save MANY frames - that way you'll have access to many potential "cuts") or save it manually frame-by-frame e.g. with Media Player Classic. Keep in mind that animated sprays cycle VERY slowly and you have that file size limit so after the whole ripping you'll have to select e.g. one in every 3 frames or something like that depending on the length of the scene (I think I had to take only every ninth frame for m1nn0's spray =). Resize all of them to an acceptable (square - e.g. 128*128) size and name them sequentially - for that task Beneton Movie GIF and Freecommander will probably be your best friends. Fire up VTFEdit and simply import ALL the pictures you created instead of only one (follow Shizz' tutorial if in doubt).
PROFIT!

Yes, I realize that the movie stripes should be at the left and right and I should have blurred or animated them. :-P
If some info about optimizing animated spraypaints got lost you can probably still track parts of it in the "deleted scenes" topic (members only):
http://forum.specialattack.net/viewtopic.php?f=8&t=3808 (especially my last and second to last posts). How ironic, by the way. :-P
P.S. Please, please, Futari, don't tell me all of the above will be used to make another anime spray - there are thousands of them. ;-)
