The cache limit is for individual files, so you get jquery down under 25K, then use CSS sprites (with images less than 25K) for backgrounds - the total cache size is 475K (a maximum of 19 components can be cached). Gzipping doesn't count (the limit applies to uncompressed code) but minifying is a must I guess.
