Ok first profession: Profession is a job you did before becoming an adventurer, cook, bowmaker, merchant, etc. I'm giving you 10 free skill points to put into a profession of your choosing.
Second the bow ranger and the two weapon fighting ranger. Yes there are two paths you can choose as a ranger. The differnt paths allow you to get different bonuses for your specialization and if you choose one path of course you can still use the other weapon. Ex: A twf ranger wants to shoot an arrow, just fine. Ex: a bow ranger wants to use two short swords in combat he takes a -4 on his primary hand and a -8 on his off hand, as the twf ranger is given the twf feat at second level so he only takes a -2 on both attacks. At lvl 6 he gets improved twf which allows him to swing both swords twice giving him a total of four attacks taking pelaties as follows: -2,-2,-4, -6 this is assuming that you are using a light weapon in your off hand, ie shortsword. So you can weild a long sword in your primary hand and a short sword in your off hand. You could wield two long swords but they are not light weapons and I wouldn't reccomend it even with the twf feat. What the bow ranger gets are archerey feats ie point blank shot at level 2 which gives you a +2 bonus when firing at a target within 30ft and at 6th level precise shot which negates the -8 penalty when firing into melee combat. Either way they both have excelent qualities. I myself prefer to take the twf path but that's because I like to multiclass as a rouge for sneak attack, the tumble skill and the rouge's high skill points at first level.
There is no instance, no faccet, no moment of life that can't be improved with pizza.
