Yes, you play as the Arbiter in certain halo 2 campaign levels. I believe there are mods too. You can also select Elita as a character model in halo 2 multiplayer.
It is not like the multiplayer map pack. Halo 3 Recon is a new game that depicts a new campaign as an elite ODST unit during the events of both Halo 2 and 3.

No, they are two completely different multiplayer setups.

yes
Indeed, Halo: Combat Evolved for the Xbox is multiplayer.
Nothing. The multiplayer map-pack is an add-on. Which means you can't play the Multiplayer map pack without Halo 2. The only thing that is different is the maps, that get downloaded to your Xbox when you boot up the multiplayer map pack. The models, textures, gameplay is all exactly the same.
Probably not ONLY covenant, but Halo 2 already has about half of its levels where you play in the life of the Arbiter, one of the Elites shamed after losing the first Halo ring. Both Halo 2 and Halo 3 allow you to play as an Elite in Multiplayer, and Halo 3's co-op allows you to play as the Arbiter for the second player. I hope this answered your question.
no you cannot
