Here's what I got:
Samuel: 33
Nephi (son): 88
Alma the Younger (R): 39
Alma the Younger (E): 50
Amulek: 26
Zeezrom: 50
Ammon: 181
Abinadi: 30
Alma the Elder: 48
Captain Moroni: 129
The point calculator linked by Spriggan did not include Exploit Weakness as one of the powers, so I substituted Enhancement for calculation purposes. I figured Enhancement is to Perplex as Exploit Weakness is to Outwit, and guessed that Outwit and Perplex were balanced costwise.
Helaman: 78
Teancum: 54
Nephi (brother): 62
King Noah: 20
Kishkumen: 63
Nehor: 51
All the figs where it's not specified already I used Experienced for the experience level of the fig. There are some changes that could be made to the article:
1. If the points get written in, the blurb towards the end about not knowing how to calculate points should be erased.
2. On Nephi (son) and Abinadi I made a mistake originally, thinking force blast is an attack power. It's actually a movement (speed) power.
3. On Nephi (brother) I included Invulnerability as a damage power, and it's really a defense power.
Another note: Nehor and Captain Moroni might be little cheap pointwise, as I don't know if the calculator recognized that having telekinesis/mind control and two ranged attacks is significantly more powerful than those powers with one ranged attack.
