There is no best way to train an assassin. Each build has its perks and its downfalls.
Personally, I prefer Trap Specialists, while some people like Martial Artists or pure Shadow builds. It all depends on your playing style. If you specify what kind of build you want, I'm sure there are experienced people here that can help you.
As for cool items, I guess you mean "Ladder only" items. I think I saw on this forum that those items can also appear in single player games, so you're basically not missing much.
