Bluetooth and IR reciver

I have bluetooth setup on my desktop and I’m looking for some suggestions for bluetooth hardware that works with SUSE. I was planning to get a PS3 keyboard and headset when I was using Windows but I don’t know if they work with Linux. Also I have a Logitech Harmony 550 and I was woundering what is the best IR reciver and do I need any special software to get it to work with SUSE?

I’m running SUSE 11.3 and KDE 4.4.4 and I use VLC for playing music and movies.

Thanks
Dan
