[LAU] Wireless Midi Controller / Linux Compatible 'Professional' Sound Card

Hi guys, I have a couple of questions regarding new hardware that I want to purchase. Can anyone recommend a good wireless midi controller board. It can be USB or MIDI and doesn't have to be compatible with Linux (though preferably it should) I just want a few knobs, buttons, sliders. Nothing too fancy. Can anyone point me to a good recording sound card for Linux. I have outused my cheap $15 sound card. Preferably something with multi-channels, low-latency, and a nice front panel interface (or external interface so I don't have to plug things in/out though the back.) I would like it to take 1/4' audio plugs as input. No need for wireless audio. On my windows DAW I have a Sound Blaster X-Fi. I heard there are beta drivers for this card for Linux. Has anyone tried them? I may just get a new windows sound card and put the X-Fi one on my Linux box if it's stable enough. Thanks in advance!
