Optimsing a gestalt mounted casting and sword and board.

[Hazzardevil]

I have a mounted sword and board caster and I'm trying to come up with some good items.
I'm mostly a ranger mounted on a drakkensteed with a phyrizzian companion for scouting.

So basically I control the following.

Me,
My steed,
My cohort
and my animal companion.

I'm level 22 in a high power game and need good ideas for a melee weapon, a bow and a shield.

I have virtually limitless money at my disposal and I'm a cunning bastard running a kingdom.

Also I need help building my cohort, she's level 20 and I want her to be essentially my assasin, 2 requirements:
1. Must be able to fit in socially.
2. Must be able to get in and out again without being caught, Her main weapon should be her EB with iterative attacks.
