I always start the game as Neutral but end up becoming Good through my choices, when starting the keep setting recruitment standards to High than training until they reach "Best" and recruit Katriona ASAP and set her to Special Missions and when your training gets high she will offer a better training program netting you "Best of the Best" but you cannot recruit everyone your standards for recruiting have to be "only the Best".
Obviously your people need armor and weapons so recruit Edario & Jacoby to run the smithy and get them equipped right away.
By the time i get Best training and Basic weapons and 2nd armor upgrade the first mission unlocks for them to get done, they should do well with best training and upgrades but try to stick to the main quest to get all the potential Sargent's (Bevil, Light of the Heavens & Jalboun of the Two Blades).
Send Bevil on Patrols, Light will work anywhere but i choose training the men & send Jalboun on Special Missions to send him away from the keep as much as possible as he can be negative for the men if staying at the keep but he increases Special Mission success.
Keep taxes low and on certain occasions Kana will ask about sending out people to collect extra taxes and i pay that out of my own pocket to keep the people happy and sending more Volunteers.
When Uncus arrives to start a shop and offers to help you run a corrupt keep i say no, he complains about high road security which makes his desire for corruption more difficult and i don't need him.
During Neverwinter's evacuation a lady named Joy will be dancing in the streets, recruit her to dance at the keep to make people happy.
Stick to patrolling Land & Roads, upgrade roads to full to allow Merchants, when signing a Merchant charter i choose "The Circle of Friends" as they don't engage in dodgy dealing.
When contacted about signing a charter to start a village you are required to keep the lands safe to keep them happy and they will later send Volunteers your way and this will grow over time and you should have several hundred Recruits and hundreds more Volunteers over time.
By the end i have over 1000 men including Recruits & Volunteers equipped with the best armor and weapons.
this is a list of my choices so they don't reflect an evil playthrough, anything I've left out like locations of people can be found here http://nwn2.wikia.com/wiki/Crossroad_Keep
