Do percentage bonuses stack?
I currently have three items that give a percentage bonus to Magicka Regen:
- Archmage's Robes: 100%
- Morokei: 100%
- Ring of Resurgence: 80%
Are these bonuses stacking? Or should I drop the ring and one of the others because they're superfluous? How does bonus stacking work in Skyrim?
Solution 1:
Yes the bonus's stack,though during combat they do recharge just a little more slowly then when out of combat but with higher stats like your using you won't notice the slow down really. It's a very good way to have an almost limitless supply of magicka. the stacking works different for magicka regen as opposed to say weapons and such. here are a few links to other such stacking...

Solution 2:
I'll specifically address the bounty comments.
Are there differences between stacking perks, stacking enchantments, and stacking a combination of the two?
Yes.
Perks stack multiplicatively with themselves, so for example the "Agile Defender 5" perk, which increases Light Armor rating by 100%, when combined with "Custom Fit", which increases Light Armor rating by 25% when wearing a full set, will result in a 250% total increase in Light Armor defense.
On the other hand, enchantments and potions use the same effect, which you can see under the "Active effects" tab in the "Magic" menu, and they will all stack additively with themselves. So for example a "Fortify One-Handed" enchantment with 20% strength, when combined with a "Potion of Fortify One-Handed" with 40% strength, will result in a 60% total increase in One-Handed weapon damage.
These two categories stack multiplicatively with each other, so drinking a "Potion of Fortify Archery" with 50% strength while having the "Overdraw 5" perk, which increases Bow damage by 100%, will result in a 300% total increase in Bow damage.
