Nice background, Nomad D2! Very cool!
Saw your questions and thought I might help Hammer out. So, here are the answers to your questions as best as I can tell.
1. Money for equipment? I haven't picked much yet.
Hammer has said we can equip our character with whatever mundane gear we deem appropiate... within reason. I'm not sure that a chain suit would be appropiate (at 200 gp), but a scale mail is within reason (at 50 gp), I think.
2. Two swords at once? Longsword and shortsword. In Xenophobia deftness allowed both. Penalties?
There are rules for this in the combat section of the C&C PHB. Basically, anyone can weild two weapons at the cost of a -3 attk penalty to your primary hand and a -6 penalty to your off hand. Your DEX modifier helps offset this penalty. So a DEX of 16 (+2 modifier) would leave you with a -1 penalty with your primary hand and a -4 with your off-hand.
3. Half elf secondary attribute modification – if applied to dexterity – would it apply to armor class?
Good question! I don't know. In addition to that, would the secondary atribute modifier, if applied to DEX, also add a +2 to ranged attack rolls and help offset the two-weapon penalties? Hammer?
5. Lots of Chain stuff listed under armor usable for a ranger = Full Chain Suit?
No... it's not listed under the "armor allowed" section of the Ranger (pg 13). Well, actually, you could wear a chain suit, but then you couldn't use your ranger special abilities...so that would suck...
6. What do we do about Secondary Skills? – For example Oliander’s history suggests horsemanship.
Nothing listed in the book with regards to secondary skills. Everything in C&C is based off your attributes. I would imagine if it came down to it, if you needed to roll a "horsemanship" check, the DM may have you roll against your INT, or maybe WIS, and would add a situational modifier (in the ranged of +2 - +5, likely) due to your background.
7. How many weapons is he proficient with? I can't find that anywhere
He can use any weapon with equal proficiency.
Hope that helps!
