While GIF doesn't support per-pixel alpha values, You can make palette entries entirely transparent or opaque, but it's only a 1bit flag - the pixel is there or it isn't. You should be able to make palette entries transparent with a menu option of some kind. Dunno, tried Paint.Net years ago and threw it out in preference of Gimp.
Also, for what it's worth, you'll get better compression with PNG, which uses the deflate compression scheme rather than the LZW one. As an example, the CP icon is a 4,795 byte gif. Converted to a png, its just 3,966 bytes. Depending on the material to be printed, you may also benefit from an image format that allows for colour-profiles to be embedded - important for accurate colour representation during print.
As for mapping the colours back to their original (desired) values, you may be able to posterize the image to the number of colours actually present. The final colour will be determined by the avg of the relevant pixels, so you should expect the colour to drift a little from the desired one. You can simply edit the palette after posterization such that it reflects the desired colours.

Use Paint.NET and save as PNG.
Select the 8-bit option when you are presented with a selection of bit depths for storing the image.

You could use IrfanView to convert the TIFFs. It's free, incredibly powerful, and has a batch mode. You should use PNG for your output files as has been stated. IrfanView has a 'Decrease Color Depth' command which will reduce the output size considerably.
What to do about the transparent areas is another matter, you'd have to do that part manually. PNG supports transparency.

I would strongly suggest using 8-bit PNGs rather than GIFs as PNGs have better compression.
For converting TIFFs to 8-bit PNGs (or GIFs) you can use GIMP with the Save for Web plugin. This plugin allows you to customize how the 24-bit image is converted to 8-bit indexed color in many ways, such as choosing the type of dithering, number of colors, etc. while giving a realtime view of the resulting image and its filesize.
GIMP also lets you posterize the image before exporting it, in which case you can set exactly which colors will be used.

Excellent: very entertaining.
What was better were the previews for Star Wars and Batman v Superman. BvS looks AWESOMESOMESOMESOME!!! Oh, and I have no idea why, but people cheered and clapped at the Star Wars trailer and even I had a wee tear in my eye when Harrison Ford turns to Chewie and says "We're home...". Or maybe it was "we're back...". Well, you get the idea...

In a way. He managed to convince the shark that he was not the seal it was looking for. Ask the shark which part of his behavior exactly made taking a test bite unnecessary.

First, you are swimming in the ocean, looking for today's meal. Then you see something that might be a tasty fat seal and get a little closer, just to be sure. And then the seal starts kicking, punching, screaming and polluting the water. What manners!

I've heard of stories where surfers punch a shark in the nose because that area is sensitive and throws them off. Kind of like a kick in the nuts.

Try to jump before a van coming down the road with 30 mph and stop it by giving it a good smack on the hood. That is about the mass and speed of an attacking white shark and the van does not even try to bite. The surfer only survived because the shark was still trying to figure out what he was. He would have had no chance to fight off a serious attack.

Yes you're correct - if the shark is attacking he's toast. Otherwise you have a chance.
