Nero CD Burning Question

Hi, I have just purchased a new cdrw that uses Nero. I am very happy with the software, however its taking a little getting use to. I have two questions,
1) How do you get track info to read on a burned CD-R when playing in an track info enabled stereo system? Everytime I burn mp3's to a disc it comes up as "track 1", etc.

2) When burning an audio cdrw I cant find the option to "close session" when done recording. I think it is by default on a CD-R, but when I burn a CDRW and play in my stereo, it displays it cant read it because the session is still open, Thanks in advance to anyone who can help with these issues.
