The processing section allows you to have the queue:
1.) Equally try to download/upload (default) or put a priority on either
2.) Change the times for waits between WU downloads
3.) Let's you set what time it should start trying to upload/download (you can have it set to a specific time period)
4.) Let it perform pass-through (default) - where any results coming in will immediately try to upload (I have mine for disabled)
5.) The rest of the stuff you could leave as is unless you want to save a copy of each result and have it report results for more stats goodness on the Setiqueue stats site.
There's alot of settings you can mess around with but it may take you a little time to find out which settings work best for you.
