Ok, after reinstall and uninstalling maraschino I got about 15-25% CPU Usage during screensaver so anyway it's much better than 75% Thanks for help.
P.S. I just installed Xbian-subtitles, that's the only addon I need, so let's hope this one will be ok, but it added few other folders in my .xbmc/addons folder:
script.module.beautifulsoup
script.module.mechanize
script.module.requests
script.xbmc.subtitles

And about memory usage: I got abou the same as CPU on xbian 15-25%, overall I got ~12% free memory on my Pi, but I think it's not a problem right? (I got 2x sickbeard running and rtorrent - sickbeard's are using about 15-20% ram each in idle.)
It seams that XBMC is holding 15% memory constant in idle.
