Well, in terms of the mechs themselves, you can certainly use an emulator on your computer to take pictures as reference (pretty sure some other members can help you with that as I've never gotten the ps2 bios to work!).
As for an artbook, there was a recent one that was released with Last Raven Portable (Some scans here thanks to Niji and NiX). There were also older artworks dating back to AC: Master of Arena, but it may be difficult to get your hands on one of those after all those years.
