When Lurking for public releases, be sure to check to see the poster's post count before downloading from them. People with less than 10 are possibly up to no good. As I am posting this, Bobu Boob has a Post count of 1,062 and mine being 14 :p.
Be sure to install Autoit3. It is pretty much the most used language for botting Guild Wars to my knowledge.
Arenanet has seemed to stop caring about botters (E.G. tremendous amount of JQ bots and Advertising bots going unpunished). It just matters about what you are botting that might hurt your account. I remember reading about a particular War Supply Bot being ban worthy.
Safely, for money, you are better off buying a factions key from elitepvper store and using it to bot JQ for Zkeys. Then try to trade your zkeys for ectos (1:1 ratio). If it is gold/plat specifically, try selling about 10 of the ectos for 100k at a time (ectos prices will likely fluctuate).
