Explanations(What does these settings actually mean)
>Cache hits to this website...
Enables caching
Use mod_rewrite to serve cache files
Fastest caching method, uses mod_rewrite rules in client's .htaccess file
Compress Pages
Super Cache files are compressed and stored that way so the heavy compression is done only once. These files are generally much smaller and are sent to a visitor's browser much more quickly than uncompressed html. As a result, the server spends less time talking over the network which saves CPU time and bandwidth, and can also serve the next request much more quickly.

304 Not Modified browser caching
Indicates to the client's browser whether a requested file has been modified or not 

Don't cache pages for known users
Logged in users are not cached

Expiry Time & Garbage Collection

The default setting will allow cache files to age 1 hour (3600 seconds) prior to being removed which is ideal. This setting can be increased for sites that do not have many posts (1,000 or less ) if you do not update your content often. If you have a very large amount of posts ( 25,000+ ), a lower setting around 1800 may be more viable to prevent stat/CPU issues due to the amount of files being created.

Rejected User Agents
It is recommended that you do not remove the default user agents from the list, to prevent bots from caching content and pages not normally seen by your visitors. (For example, if you have a calendar, a real visitor may only browse months close to now, but a bot will index every month forever as if it is a different page. Caching these pages real visitors are unlikely to visit wastes resources.)
