Sadly i do not know much about this.... but very few modelling applications can use .X as far as i know (which is the format you need)
And to make them FPSC ready is apparently very hard
But there are lots of free and very cheap model packs available on these forums and at fpsfree (google search it... can't remember if it's .com or .co.uk or .co.nl or whatever)
And learning to use modelling applications takes a VERY long time.
However... one thing that can work.. is to copy the entity folder for... say... a crate... then use a paint program (it needs to be able to do tgas) to edit the texture... open FPSC and you will see it in your library. (Note: you may need to edit the sample picture aswell(this is the picture you see when you are browsing your library for entities))
Sorry for the multiple brackets
