Use: 48000 sample rate. Install a realtime kernel for audio usage, and the 
clicks will vanish. Use jack for your audio recordings and alsa for normal 
music playback (can be jack, too). For skype you have to use the oss 
emulation modules, they don't support alsa yet.

Ps: Your ram problem can be solved by updating to 512 for example ;-)
