Hasta La Motion!

I have multiple formats of RED footages in 2k, 4k apart from that DPX files in 2.35 Anamorphic format and DSLR footages too.

We would like to do the full post production within Adobe CS5 Suite. Edit in Premiere, Compositing & Grade in Aftereffects with color finesse.

Our final output would be in 2k DPX sequence Master @ pixel aspect ratio square – 2048X872

My doubts are as follows :
1.) While working we would need to PAN & Zoom in RED 4k files. Is that a good practise to do it in premiere cs5 ?
2.) What are the recommended project setting & Interpret footage settings ?
3.) I have planned to import all the footages as it is to Premiere and assume them as 24 fps using Interpret footage settings. Is this is a good practise to do it in premiere cs5.
4.) Since my output will be 2k, can i modify RED 2k settings to 2048X872 @ 24 fps @ pixel aspect ratio square and continue to edit?

I have already gone through this article
DAVTech Table – Editing with RED 1.7 Technical Overview. It discusses only about RED.
