those skills are probably useless? also they might not be implemented (yet) on aRO--where you got that info might be on a more updated site that is concerned with more updated episodes
for knights, there is really only 1 way to go (unless you are uber rich)
use the strongest 2h sword you can find and stick with 2h quicken, awakening/zerk pots, aura blade, and i'm not sure if there are any skills i missed (because i think the rest are for Lord Knight only) and get a peco with max moving hp recov
for training you can go to Isis if you can handle it and bowling bash with tons of GJ and Meat (very costly, not recommended unless you have a healer/support class with you) r you can go to bibilan-last level and train there. you might want to get fin helms from Obeane in the level before the last (bibilan) because thats always a good noob drop.
if you really don't care to do that, get lots of dex, str, and int, get a super strong spear thats good versus undead, and KS in GH prisons with spear boomerang
besides all that, knight isn't a good class--in fact, one of th worst--with which to start a server. I recommend that if you don't already have another on which to make money, do so now and worry about the knight later. knights are HELL to level, especially without funding.
good money classes are assassins/rogues, hunters, and priests--those are always great to start with because they offer a lot in skills when you lack in gears
