2001fp - Non-native Res. question and Portrait mode question

I have two questions:

I currently have a 2000fp and a 2001fp hooked up to my machine. I've been trying to figure out which one I want on the digital and which one on the analog as well as which one to be primary and which to be secondary. When I play 3D applications in non 1600x1200 resolution on the 2000fp, it seems to do a bit of filtering on the final image that helps smooth out the overall look. When I do the same thing on the 2001fp, it doesn't do the same filtering and instead I get pretty much the exact scaled pixels. I would prefer the filtered look, is there a way to get the 2001fp to act the same way?

Also, from the posts here I was able to get portrait mode working and really like it for programming and reading documents, but unfortunately the performance hit is just too much to justify for me. Loading a new page in NetCaptor/Explorer, loading new email messages in The Bat, etc all cause the input to freeze for a second or two. Are there any suggestions for solving this or is that just the way it is?

Thanks.
