spot on lens and need eyes whitened

I use premiere pro, so I figured this would be a good place to post. I'm editing my feature film, and picture is pretty much done except for two things: 1) I have a blood spot on my lens for a couple scenes and need to get it out, and 2) It's a zombie film, a low low low budget zombie film, and since all white contact lens' are expensive and I had over 100 extras in the film, I'd like to white out the eyes of the zombies in post.
I've attempted to do both things, and either really came out looking like I wanted it to. I tried exporting the blood spot footage as a filmstrip into photoshop, but the spot came out looking like the predator when he turns invisible: You can't really see the spot anymore, but it's replaced with the outline of the clone stamp.
I've also tried to export frames for the zombie eyes, and while it works for the most part, it takes a long, long time to do so, and it's hard to get each frame to transition into the next without the white eye bouncing all over the place, I.E. when I white out each frame in photoshop, it's damn near impossible to white each eye the exact same as I did in the last frame.
Is there a more time efficient way of doing the latter? Is the blood spot removeable at all? Help!
 
You need something like After Effects for both things. For the eye there is a way to motion track their eyes. Look at this tutorial

For the blood spot it might be very difficult to remove if you aren't able to generate a clean background plate. Painting frame by frame over the shot might be the only option.
 
A big issue I had with clone stamping the spot was that it would show up as a different shade of what I cloned. For example, I'd clone a white surface, and when I tried to apply it over the spot, it came out with a bit of shade to it, not the true white that I had cloned. I've never had this issue with clone stamping before. The other issue is when the spot is over two different surfaces, like in the subject's hair and right outside the contour of the hair - it's really hard to nail that consistantly. Thanks for the tutorial link, I'll take a look.
