Take a look at the Wiki on the page Mystic Forge. It will tell you where the forge is, how it is used, and some predictable recipes. The forge lets you do two things. First you can create recipes to craft other items like consumables, weapons, or armor. Second, the forge can be used to create better crafting materials of one type higher.
The examples the wiki gives are as follows:
Common Crafting Material Promotion
Common crafting materials can be promoted to a small pile of higher
tier materials with the following formula. The tier of dust needed is equivalent to the tier of the wanted product. So, if you are hoping to create Orichalcum, a tier 6 common material, you need to use Crystalline Dust, a tier 6 dust. If common crafting material B is one tier higher than common crafting material A, then:
10-50 Crafting Material B = 250 Common Crafting Material A (i.e. 250 Mithril Ores) + 1 Common Crafting Material B (i.e. 1 Orichalcum Ores) + 2-5 Dust A (i.e. 5 Pile of Crystalline Dust) + 5 Philosopher's stone
In that example: That recipe will produce 10-50 Orichalcum Ores
Armor boxes and armor satchels
Recipes can be created using the Mystic Forge. They will allow you to
craft armor boxes and armor satchels, which will in turn give you
every piece of an armor set.
Armor set recipe
Ingredients
5 Bottle of Elonian Wine
20 Arcane Crystal
50 Mystic Coin
1 Armor item
Mystic coins seem to be a common item needed for Food Trays, Weapons and Armor. Also look at this page for current recipe research.
You can see this in action with this video on how to make a Giant Chocolate Cake. Details are in the video summary.
According the guild wars 2 Wiki
The primary source of influence is through participation in PvE or PvP:
2 for individual guild members completing an event or part of a personal storyline. (The per-player influence gained increases substantially with each new participating guild member.)
5 for individual guild members getting a victory in a pvp match.
10 for each accepted guild invitation.
10 for each member who is online during an Attendance Check.
Non-participation sources:
10 can be purchased from a Guild Promoter for 2s (in various increments).

I'm afraid you're mistaken, sorry to say. Each race only has one voice actor each for the male and female roles; they do not vary by class.
The voice cast is as follows:
Human PC Male: Nolan North
Human PC Female: April Stewart
Charr PC Male: Ron Yuan
Charr PC Female: Kate Miller
Norn PC Male: Matthew Mercer
Norn PC Female: Claudia Christian
Asura PC Male: Steve Staley
Asura PC Female: Julianne Buescher
Sylvari PC Male: Brandon Bales
That list was taken from a forum post during beta that I saved on my PC, so unfortunately I can't link to that particular source anymore, but this post (regarding the amount of resources they'd need for more voices) on the current live forums confirms it as well:
