If I saw those clips without reading this thread, I would probably assume it was just a jittery playback.
It sounds like your work flow is pretty solid, so there’s no reason to assume any problems were added by the transcode. What you need to figure out is if the (slightly) less than smooth motion is what was actually recorded, or if it’s a playback issue. I don’t know of anyway to tell for sure without testing it meticulously in different players/formats.
If the jittery motion was recorded in camera and it really bothers you, then I would look into Mocha for After Effects. There are some relatively simple ways to smooth out simple camera motions like this. It’s not perfect, and it doesn’t work on every shot, but it’s worth a try.
Either way, those shots don’t look too bad. Nice shooting.

Is there any scaling involved in your exports?

For what it’s worth, the reason that the 5d has so much trouble with moire patterns is because of the recording pattern the sensor uses in video mode. There is no workaround.
Google “line skipping” if you want to know more.

What most people refer to as strobing is caused by an inconsistency between the camera’s frame rate and the flicker pattern of the lights used.
If that’s what you are talking about, then questions to ask are: What if any lights are you using? Are you in the right part of the world to be shooting 25p? Or is this a different problem altogether?

By the way, the MPEG-2 Playback Component is only $20. I don’t actually have it, so I can’t really vouch for it.
(For broadcast work I use Episode with broadcast presets provided by the client).

Simple is a relative term. I have gotten descent smoke effects using fractal noise, but usually only for a really subtle look.
There is a smoke preset that can be tweaked to look almost OK. If you play with the settings, blend modes, and mask it right, you might get an acceptable effect.

I have Mocha for AE, which was free with AE CS4. It is limited in that it can’t export video, but doesn’t limit the exporting of tracking and corner pin data.
Are you using CS4+? If so, your licenses might not be installed right.

Just make sure to keep your keyframes to a minimum, and try to match them to the motion of the actor’s head. The number one thing that gives away a bad roto is jittery edges.

If I’m following you correctly, you’re ball is parented to a null and offset so that when the null rotates the ball moves in an arc, right?
Personally that doesn’t sound like a great way to do it. First of all, those arcs will not be parabolic, just round. Second, what’s so hard about using position keyframes? Using bezier curves with handles, you can basically draw a path with way more control then your current method.
Unless I missed something.

H.264 is pretty much the only web HD format. The quality is going to be affected mostly by your bitrate settings.
Also, it’s difficult to know what you mean by “trails.” If they are in fact compression artifacts, then you need a higher bitrate setting. However, since I don’t know what trails are, I assume it could also be a framerate or interlacing issue. Can you post a frame?
One last thing, when you say you “de-interlaced” the video, do you mean reverse telecine, or did you actually use a de-interlace filter? Your 16mm footage should have been telecined with a removable pull down pattern. In other words, you should be able to fix the visible interlacing without any loss of quality.
