What should the equip cost be? I am trying to avoid this from being a do-nothing crap card, but also don't want it to be at the level of bannably good either.
Mystic Ring of Samasz 
Legendary Artifact - Equipment
As ~ enters the battlefield, choose a color.
Equipped creature has protection from the chosen color.
Whenever an equipment is attached to a creature you control, attach all equipment you control to that creature.
Equip (?)
The effect seems to be ... not very effective on its own. I could see it costing 
to cast and 
to equip. The second ability works without it being attached to anything.

Sounds good to me! I guess my own experience with broken equipment synergy made me a bit hesitant to make this too powerful.

That sounds like a great idea! Here's the updated design:
Mystic Ring of Samasz
Legendary Artifact - Equipment
As ~ enters the battlefield, choose a color.
Equipped creature has protection from the chosen color.
Whenever an equipment is attached to a creature you control, you may attach all equipment you control to that creature.

It kinda depends on the format you're shooting for, as the card's power scales directly with the legal equipment cards.
Also, because of the second ability, you will always pick the lowest equip cost of any artifacts you control. It might be this card, but if you have Lightning Greaves, this card has an effective equip cost of zero.
For CMC 4, I think the equip cost should about 3.

No more than
. Comparing this to any sword of X and Y, I do not really see the benefit of making everything into Kazuul's Toll Collector, especially at that cost.
