yea, right away i can see that it was disk space you're running out of. do you host a lot of images, mp3's, or videos? most websites don't take up that much room unless they host those types of files.

the disk space isn't a huge deal though. unless it's could be if the logs are filling up or being rotated which creates several small files. if you have a large number (not size a lot of files) of files on your server that can start causing problems. have your system admin / web person look at the logs and clean them up a bit.

the fact that you're only using less than half of your RAM ( the last bar 372 of 1GB) but your cpu is at 100% means that it's a pretty save bet that you need to tweak my.cnf. that will make it so sql uses more memory instead of cpu and in turn cut down on cpu usage.

it might very well be a mod that's running some hard mysql quires really slowing things down beyond the my.cnf tweaks. i didn't see a lot of mods right away on your site but i don't understand the language and i'm not logged in so i really have no idea.

so to sum things up.. currently i would suggest cleaning up the log files and make sure my.cnf is tweaked to handle your mysql quires.
