Highest/Bestist quality ...Save as...?

I think the quality would descend in the following sequence:

tiff -> png -> bmp -> jpg (depending on compression) -> gif

roughly in line with descending filesizes. However since you aren't really dealing with the source material directly, i.e. the RAW data from a camera, or the vector artwork that was used to create the bits and bobs in the first place, your quality will be largely dependent on the quality it was originally saved at, and all you can do is minimise further loses of clarity.

Further to impr0v's reply,
tiff, png and bmp are "lossless", meaning that when it is saved you can always reproduce the exact image.
When you save it as jpeg and gif (both "lossy"), you loose the qualily and can't get it back again - like taking a blurry photograph.

There's a very good reason why you mostly came accross 'tif this and tif that' in your research - Tif is the industry standard file format, and use eps if you are combining a photograph (raster info) with text or graphics (vector info). Don't use any other file format, you'll be screwed if you need to get stuff printed elsewhere (particularly litho, as imagesetters hate compression). Don't generate text or graphics (logos) in a raster editing program such as photoshop - use illustrator or similar and save as an eps.
Oh and all files should be cmyk rather than rgb (web images)

These are just the basics
