Point breakdown:

d12 HD: 50/50
Weapon proficiencies: 25/75
Armor proficiency: 10/85
10 class skills: 10/95
4 base skill points: 30/125

Code of Honor: -15/160
Multiclass restriction: -10/150
Spell capability: 10/160
Limited spell list: -10/150
Spellcasting starts at level 8: -20/130
20 divine spells at level 20: 20/150
Monk saves: 35/185
11 bonus feats: 55/240
If I really wanted to make the class bad, I'd add an alignment restriction (-10) and drop the Simple Weapon Proficiency for a bonus feat at 1st level (like Simple Weapon Proficiency) (-10/+5) for a total of 15 points; this would give the class "divine grace" per the paladin ability and perhaps another bonus feat (at level 5, I guess).
