No one replied to your thread yet, so I thought that I would.
I'll just give you a few tips, and you can contact me if you need anything else
For levelling, the notorious bot is the 'Undead Pirates' bot, but recently a bot names 'Timespace XP' has been taking over :P
Both are good
For gold, it was recently very easy to bot, until the bot stopped working as the map it was set in, was deleted
There is a "Forestchaos" gold bot, which is OK, but it could be better
Hopefully someone will find a new place to bot soon
For what classes you should get, I recommend that you look at AQWiki's full list of classes as they're all there
Anything above the starter classes is pretty good, but of course there are some better than others, but that depends on what you want to do
e.g farming, PVP, soloing etc.
Other than that, just mess around with the trainer and you'll get back into it pretty quickly, I'm sure
As I said, if you need anything else, just contact me
