If I would go for a 2h/thrower cavalry, I would go this build:
Level 30 (4 420 577 xp)
Strength: 21
Agility: 15
Skills to attributes: 2
Power Strike: 7
Athletics: 3
Riding: 5
Horse Archery: 2
Power Throw: 7
Weapon Master: 5
Two Handed: 100
Polearm: 124
Enough damage, enough HA, and enough Throwing wpf to have some armour.
As for lvl 33...
Level 33 (35 569 612 xp)
Strength: 21
Agility: 18
Skills to attributes: 2
Power Strike: 7
Athletics: 3
Riding: 6
Horse Archery: 3
Power Throw: 7
Weapon Master: 6
Two Handed: 122
Polearm: 124
34 and 35 would be attributes --> skillpoints to max out athl and get some IF.
