1. For most guilds after doing something wrong all the quest givers would advise you to "See {so in so} and "Make Amends" to get back into the guild". First the punishment is like 1,000g then more and more. Maybe after 10,000 they will just ignore your requests.
But quests and benefits for the Temple are that after you complete the weird pilgrimages and move higher up the quest givers tell you of extrodinarily hard to find places in the world where most of the super enchanted weapons are, or amulets, etc. One being a favourite of mine, the Skullcrusher, A mace that has contant effects of feather and fortify mace.
2. Being invited into Vivec's quarters is essentially one of the turning points in the game. If you've started the "Blades" quests thru Crassus Curio (sp?) that old guy who asked you to get information about the Sixth House in the begining in Balmora then you basically just have to continue those quests until Vivec does send for you.
3. The Heroes, the other people whom are like Vivec are Sotha Sil, and Almalexia. If you have Tribunal expansion pack, then you get quests from Almalexia, and well see both her and Sotha Sil. Almalexia is in her Church like building with the most deadly High Ordinators (guards similar to Vivec's) in the game. I believe she has a dozen around her.
4. I love morrowind, but sadly my xbox is pretty bad at running it. Wish I had a nice computer to run it on, but I'm basically waiting for Oblivion :

:
Character wise I love the Khajiits and Dark Elves. The Thieves, Assassins, Telvanni quests are of my favorites. And the entire Bloodmoon expansion.
Sneak, Alteration, Destruction, Short Blade, Light Armor. Favoring Agility, Speed, and Personality.
Basically Thieving little spellsword like assassins. And the Bow isn't all that bad.
