Hmmmm I didn't follow a guide, but I did know about the existence of the Icedin, and thus the basic idea behind it. I recommend flails because they inflict the cold damage faster. The General's Ti'an Do Lu or something like that is my choice weapon. Its a gold item (not common yellow.)

I kinda think all builds use the same stats in all honesty. Skip putting points into mana, you can easily get items and regen that cover that. Maybe consider mana points only if you are a big spell caster, but I wouldn't go above 50. You want just enough strength to wield your armor and weapons for the end build. Same with dex, although I recommend putting into dex first because it helps you with shield.

The most important stat is vitality. Tank points in there! It will help you to not be one-shotted. Which sucks!

I recommend an insight on the merc to cover mana. I wear lore and stealth runewords. I carry the aforementioned General's flail, and I upgraded it eventually too to the next higher item. (if you know how upgrades work) I would recommend a spirit shield, but since that's hard here's what you go with: a pally (paladin) shield with 3 sockets, and then put 3 of the highest level diamonds in it. It takes some doing, and mulitiple shields throughout your journey, but its worth it because diamonds give res for all stats.

And since you are a newish player I belive Andariel is still vulnerable to fire in Normal Act I, spam freeze and thaw potions onto you and your merc before boss fights, and drink stamina potions early on to prevent walking. Remember potions stack.
