1. I would suggest getting VIP, mirror mode. It helps with the bans i can assure you that.
2. You will have to experiment yourself with different skills, certain skills do have higher ban rate, so don't want to over do it. Use breaks!
3. Trail and error, no one is going to give away there botting strategies. One thing i can say new accounts do have higher chance of a early ban, do quests, dont bot the same skill 24/7. Change it up now and then.
4 Take breaks, be human, don't suicide bot.
best of luck!
