The BOD guide are in the forums in the new player guides section on the second page. It gives you the info to calculate the point value for any BOD and see the possible rewards for each. Very useful if there is a particular item you are trying to get or to keep you from burning through tons of materials to fill a large BOD for a reward you don't want.
I'm not much help when it comes to taming so someone else will have to help you out there, although you can always refer to
http://uo2.stratics.com or
http://www.uoguide.com for some basic info although some things will not apply to WP.
I don't think anyone really minds helping other players out although you can be difficult to find. If you get into a bind you can always say i pray for life or if you you become evil at any point the command would be blood for the inferno. These commands will let you self rez at the cost of 5 strength and some karma, which if you are resource gathering you will gain back the strength quickly. I give blood to the inferno regularly it doesn't hurt much.
As far as carrying capacity, you lokai is your friend until you are able to make/buy the keys. Just be prepared to fail a lot if you are making them yourself. At 120 Tinkering you only have a 40% chance and even at that I failed as many as 7 times in a row trying to make one, so make sure you gather plenty of materials. I made a few myself and bought a few that the materials were too valuable to waste on failing. I didn't do a ton of gathering until a had a few of the keys for storage. You can also use a bag of sending when you get heavy, I usually just used it to send gold until I got the checkbook.
As far as what I do when I go to dangerous places, I usually die. I try to be prepared I carry two bows, and my melee weapon is a kama. One bow is specifically for higher end mobs (hit lower attack, hit lower defense, high damage+ and loaded with freeze arrows) the other is for regular stuff. The kama has whirlwind special attack which is useful in a crowd and it's fast. As far as armor goes I have 2 pieces of crusaders gear-both obtained by voting, the rest are odds and ends, getting my resists close to 70. I usually carry a high level dragon to help bail me out when I get myself into too much trouble. Strategy-I'm usually in vampire form to get some life leech and poison resistance, enemy of one on tough mobs, honor when I remember, consecrate weapon a lot, and healing as needed, try not to die too much, run away when appropriate. That's just me, certainly not the best but I have fun trying and hopefully this will give you some ideas.
