Unless your photos are unnecessarily large (i.e. big imported photos scaled down), I’d say you’re stuck. That sounds like a big comp, big photos, long running time. I used to do things like that overnight.
Did you enable multiprocessing?

Try setting the keyframe interpolation (spatial) to those two keyframes to “Linear”. Check the Help.

Also consider applying the curves effect … make an “S” with the curve. Adjust until you like it.

If you can’t get a master in a high-quality codec (what are your options?), I’d use QT Player to export to one of the codecs we’ve mentioned. If it’s interlaced, separate fields and roto in a 59.94/50 comp as mentioned, then render interlaced. Check on an interlaced monitor.

If you see the combed lines, then it was incorrect to turn off field separation. You had it right the first time: separate fields.
You see, in order to scale, blur and do just about anything to interlaced footage without totally messing things up, AE needs to separate the fields, work your magic, then reintroduce interlacing or not at the render stage (your choice).
Now if you want to do roto, you should separate fields, then do the roto in a 59.94fps comp for 29.97 interlaced footage, or in a 50fps comp for 25 fps interlaced footage. Then drop that comp into a 29.97 (or 25) comp and render that.
Yes, you should convert the MPG to something like a Quicktime in Animation of PNG codec, then import that.

Beatcha tuit.

My guess is that the imported MPG (just for fun, search for “Dave’s stock answer #1”) is actually progressive, not interlaced. So you should select the imported file, and file>interpret footage>main. Then turn off “separate fields” in the interpret footage dialog.

The AE Help should handle the “how to render interlaced” concern. Video devices don’t recognize flags. If they can do interlaced, they show one field, then the other. If the clip is progressive, they do the same thing, but the two fields happen to be identical. The machine doesn’t know the difference, and doesn’t care.
The rest is determined by the playback device. What does it want from you? Does it want upper field first or lower field first? One video or two? Who is in charge of the playback device? Who knows how it works? To whom will you be giving your video?
This is the person who will answer your questions.

Find out from the client which 3D system is being used, and talk to the techies who know the system. Then get back to us. 🙂

After Effects depends on a fast processor and lots of RAM. Video editing apps largely depend on fast hard drives, but with codecs such as DV, they don’t even need that any more.
Video editing apps generally just play video footage off hard drives. Occasionally they use processor power to generate (render) new frames when effects are applied. On the other hand, After Effects uses the processor to generate all frames. All the time, every movie, for the entire movie. Every frame is generated fresh, even when it hasn’t been changed.
So the processor is key, and more processors are better, especially when you have a lot of RAM to allow the use of multiprocessing. For that you need 2GB of RAM per processor. Since you have only one processor, you can’t use multiprocessing.
What kind of hardware would you need? After checking the system requirements for CS4 or 5, you should get the fastest processors, most RAM you can afford, at 2 GB per processor. After that, have enough drives for system, sources and projects (that would be three). I won’t be more specific than that, because it just doesn’t matter. AE has always been this way: proc, RAM, drive.
… and get a really nice ergonomic chair. I’m dead serious. And consider a Wacom tablet if you want to avoid carpal tunnel issues.
There should be some hardware/AE threads already up on the COW.
