I’m not familiar with Comet Cache, but they might have a minifying option if you look.
No need to go from 4 to 8 plugins, but if you want certain things like minifying all of your scripts and styles into one file each, you’ll need a plugin if your existing ones don’t have that feature.
Doing something like that requires a lot more than a few lines of code.
Did you ever get any results from Query Monitor?
