Premiere pro. Too many audio tracks, I just want one stereo track. How?

When I work with P2 footage from my HPX170 in Premiere Pro CS4, I always get 4 tracks of audio. It´s too many, and it fills my timeline window vertically too fast. It uses too much real estate. Sometimes i delete 3 and 4, and use "punch in" from the source monitor and that works, but sometime I want to use the drag and drop function, but then Premiere creates those extra 3 and 4 audio tracks. Just too clumsy for me.

So my question is this. Is there any way I can get rid of the 3 and 4 tracks? Or preferebly conform everyting into just one stereo track? Are there any routing or interpreting functions to conform my footage to one stereo track? What are your workflows for this?

Seems the HPX is always recording onto 4 mono tracks. But someone gave me a fix on the Premiere Pro forums, on how to route the channels.

Seems to do ok with premiere. Plays back pretty smoothly 720P on my Intel 2 Duo with 2 GB ram.But have heard a lot of bad things about Premiere CS4. A lot of people are experiencing bugs with the new version. It seems VERY slow when opening, and I am working with small projects (commercials). So it must take a lot of time to load a full feature.
