Ok, I should warn you I've used GIMP all of about 15 minutes in my entire life, so I don't know the ins and outs of it like some people do. I can tell you a way to achieve what you're talking about but it's not necessarily the best or most efficient way...
That said, the time it takes the animation to play can be shortened or lengthened at this stage when you're saving the animation:
This line I've highlighted is giving you the option to change th frame delay in milliseconds. You'll notice a grave difference in the speed of your icon if it says 400ms as opposed to 100 ms.
As for the file size, the best way I've found it to get yourself the 'Optimize" plug in for GIMP. ---> http://registry.gimp.org/node/33#comments There's a version here for Mac or Windows.
You download and install the plugin and it works similarly to the Photoshop feature "Save for Web and Devices" where the program shows you what your optimized images will output as, so you can make a determination as to how much picture quality you're willing to sacrifice to compress that file size.
