Help with Mounted Archer

[PapaZorro]

Hey all, I'm making a Mounted Archer, it's for my friend's game where I'm playing a beta class he made up, so the important things to note:
Level 2 right now, going up to who knows how high.
I get bonus feats at levels 3, 6, 9, 12, 15, 18, which can be Fighter combat feats.
I was thinking Aasimar, Tiefling, or Human, if I play Aasimar or Tiefling I basically get to choose what alternate goodie I can trade out my spell-like ability for (such as +2 extra strength or dex for Aasimar).
We get 1 bonus feat for this campaign, but I already have 2 feats eaten up with non-archery related things I'm not going to change.

And I get the Mount class ability as a Cavalier.
I guess I need the most help with the Mount - can I use it's Ability Increase to raise it's Intelligence? Once I raise Int to 3 can I give it Escape Route and take that myself for unlimited ride-through without attacks of opportunity?
And just WHAT does combat-training a horse do?

I know I'm kind of scattered - any help would be appreciated, especially regarding the Mount.

Bump - anyone know anything about making a Mount?

Animal Archive has most of the information you will want for your mount.

Have you consider Sohei Monk?

Samurai is much better than Cavalier for Mounted Archery. I would highly recommend that if you don't go Sohei.

This thread has a lot of useful information for Mounts/Animal Companions.

Finally, don't actually take the Mounted Archery feat. There are no penalties on ranged attacks unless your mount makes a double move, and a single move is almost always more than enough.
