I'd like to specifically recommend the http://www.accesstoinsight.org/
website as it has loads of really interesting articles and information on it.
As for your questions: I became interested in Dhamma because after much searching it is the only teaching that speaks to my experience of reality. It is very practical, and you can see its benefits almost immediately and in every situation.
I am only a beginner in meditation so the hardest thing for me is getting the energy and motivation to practice, and then not to be distracted. Also not perpetuating unwholesome when it arises.
"If beings knew, as I know, the results of giving & sharing, they would not eat without having given, nor would the stain of miserliness overcome their minds. Even if it were their last bite, their last mouthful, they would not eat without having shared."
