If there are some corrections or more Q/A that you would like to include in here, let me know. I'm hoping that this could be used as a reference thread for countering RD, which appears to be the type of monster affix that give players the most issues
(1) What kind of damage gets reflected back?
Everything (Melee & Skills). The only skill whose damage does not get reflected back is SSS (due to invulnerability)
(2) How much damage gets reflected back?
20% of all incoming damage gets reflected (according to Diablowiki)
(3) In what form does the damage gets reflected back?
Some debate between Holy and Physical (no matter what the original source)
According to Seaboots' empirlcal testing, it appears physical is the winner.
(See http://us.battle.net/d3/en/forum/topic/7320262157?page=2#29 for how he tested it)
(4) What other monster affixes amplifies RD?
Fast(on themselves), Illusionist(clones), and Health Link(damage connected) (LordRaahl)
(can someone verify this and give rationale behind the effect of the "fast affix"?)
(5) What tactics can we use to counter RD?
have 900 LoH, 900 regen, and 2.9 LS, and you'll be immune to RD forever.
either that or get LS on both weaps, which is redundant.
Just don't cast faith in the light to buff sweeping wind, it is the culprit.
Use tactical retreats, kite, pick up globes, attack other enemies - in other words, use your Skill.
Well I am stacking phys resist despite not using OWE, and it helps greatly with RD, not to mention most damage you take is phys anyways.
- stack more EL (physical resistance, armor, vit, etc) to a point...
- stack sustain (LS, LoH, LpSS, LpS, LAK, health globe bonus, etc)
- intersperse use of different skills (serenity, healing, mantra spams with LpSS, etc)
See http://us.battle.net/d3/en/forum/topic/7320262157?page=2#23 for more detailed information from Raahl -- very informative, IMO

Blue post that states that rare minions do more reflect damage than intended:
The way Health Link works in conjunction with Reflect Damage is a bug and not working as intended:
