What the hell is going on?
Well, ALSA can be very difficult if your audio card is not detected properly. What you normally have to do is find what kernel module your audio requires. The best thing I can say is to go here:http://www.alsa-project.org/
If you find your card then you should be able to find the module that you need to enable in the kernel. You then need to recompile the kernel. Fortunately, if you're using gentoo then that process should be pretty easy.
Then you just have to load the module on boot. Once that process is done you have to edit the alsa.conf (I think that's what it's called) with your card's info.
If you need help just let me know where you're stuck and I can walk you through. Seablade here is a wiz with the audio stuff so he might be able to give you some suggestions. Now, it sounds like the card may be working, but your surround isn't... is that the issue?
As for the video card, I've had terrible luck with ATI. I get poor performance even with the newest drivers. Nvidia, on the other hand, is quite good. So if you're using ati then I'm afraid to say that you're not gonna get great performance. I successfully emerged the nvidia drivers and installed them from the installer file from nvidia.com, so either one should be sufficient.
Finally, the stuttering maybe because you didn't enable dma in the kernel. Your overlay settings also may be wrong in the xorg.conf. There's actually quite a few things that could be going wrong.
