Nearly bought FS2004 today but...

I very nearly purchased FS2004 today but would like some advice first.
I gather from other postings that it is ok to have fs2004 as well as 2002 on the same system? I have plenty of room on my hard drive, over 60GB, so I don't think that should be a problem.
I have the excellent VFR photographic senery from "Just Flight" installed for FS2002. I have heard that it is compatable with 2004 but how do you share the files or do I need to install it again in 2004?
Also, is the installation of 2004 straightforward, because if something can go wrong you can bet your life it will?
I have had some very poor frame rates in the past, possibly due to the add on scenery and also I believe some of the downloaded aircraft and panels slow things down a lot. Is 2004 more resource hungry than 2002?
Any help would be most appreciated.
My system specs are; P4 3.06ghz processor, 512mb Ram, G4 MX440 SE 128MB Video. 80GB hard disc.
All the best.
