Slitherine

I'm a recent convert to historical wargaming, and I wanted my first army to be a 28mm LRR force based on Caesar's army from the Gallic Wars.

I'm curious about the optional Illyrian MF. Does anyone have any suggestions for references describing them and/or 28mm scale models?

Also, any recommendations for 28mm models of Balearic Slingers, Numidian Archers, Numidian LH?

Here is a page concerning Illyrians
