For Amon...
1st/2nd level: He will replace everything you have from your class. The only things left are feats (you may have to spend one on Ritual Casting) and racial abilities.
You could try for a mean Defender character. You can still mark using fire damage, you retain your high hit points and armour class. If you're a human you can also benefit from Refreshing Absense as a quick heal.
Optimised 1st level binder using Amon:
Human Paladin
Feats: Ritual Casting and Refreshing Absense.
Statistics: Con and Cha.
Skills: Anything plus Diplomacy.
Powers: Anything that makes a good paladin. Include Cha based at will attacks. At level 2 Astral Speech is a much for every serious binder.
Advantages: Use Con and Cha to hit, very tough, can mix controlling with defending. If it starts to go wrong, expell your vestige to heal and turn into a real defender.
If you get an augment you probably want a Cha based melee attack rather than Ram's Counter.
At 3rd and 4th you could retain an encounter power if you got a Pact Augment and you have 1 or 2 more feats to play with.
Get Augmented Pacts for a cost reduction (maybe?) and you can keep both your at-will and encounter power with a decent pact. Additionally one of the Human feats for good action point useage, so you can get two extra bonuses per AP... if you're spending AP you usualy really need a good bonus.
You are replacing your level 1 encounter power with Amon's so Righteous Smite is a good battle opener, all those temporary Hp should reduce the need to be as much of a defender and it's Charisma based.
At level 5+ you probably want to bind something else.
