Are crucible marks shared? (Destiny)

I've searched some but haven't found a definite answer for what I want to do. Basically, I have a hunter for PvE and just started a titan for PvP. There's some faction armor for the hunter that I want, but I need crucible marks and rank. The rank is no problem, but I don't plan on using the hunter much in PvP.

I have already figured out that rank isn't shared, and that's fine. I want to know if crucible marks are shared like glimmer. Will either of these methods will work to get faction armor for my hunter:
1. Earn faction rank with my hunter in strikes and use crucible marks earned by my titan to buy the armor.
2. Earn faction rank and crucible marks with the titan in PvP, buy the hunter armor, and trade it over via the vault.

Can you buy armor for other classes from the faction vendors?
