Any Tips For "Forensic" Image/Video Work?

Hi all.

My place of work was robbed over the weekend.  We have security camera footage and I offered to try and clean up what's there, go through it frame by frame in areas of interest, and get the best stills available of the crook.  We actually think we know who it was (a disgruntled former employee, fired for stealing) but a good image would be needed either way.

Looking at the playback, the color is washed out due to low light and it's a little choppy, but it doesn't look too blurry.  It is motion activated, thus the choppyness - I think...

I planned on using a few of the programs in the Adobe suite  (I have the CS6 Master Collection).  My initial idea was to use After Effects to scrub frame by frame and pull some good ones, then go to Photoshop and enlarge/enhance as much as I can to attempt a clear shot of a face.

The footage is still on the DVR box and nobody knows how to retrieve it just yet (boss wont let me try - he's afraid to mess with the software and is asking the people who installed it how to proceed getting me a copy), so I have a day or 3 before I get the video home.

Nobody knows what the video resolution is until we get the footage off the black box and into my hands.  Yes, the police are involved, but there is no harm in my playing a bit since they are quite busy and if I can do this it would be  ...  Nifty?

My questions are:

Does my plan sound reasonable, and is there a better way to go about the job? 

Would Premiere Pro have features that After Effects lacks to make it a better choice? 

Any Plug-Ins (for Premiere, After Effecrs, or Photoshop) (or other!) I can swindle my boss into buying for me that may make a big enough difference to make it worth asking?  Example: Is something like "PhotoZoom Pro" really that much better at enlarging than the tools already in Photoshop?

Are there any workflow suggestions or tutorials for this sort of job?

I'm asking in the lounge since it does not really involve any one program, but possibly several from the suite and maybe even other, non-adobe, stuffs and is also more about workflow and techniques than individual programs.

Thanks in advance for any input or advice.
