It is easier to build/level characters in 4E, as it was designed to be more approachable for people beginning into tabletop gaming rather than the advanced players 3.5E was made for. I'm sorry to hear that you're having health problems... I think it might be a little while before this bird gets off the ground (no one has made characters yet, after all), is there a chance things will clear up in (considering how much there is against how ridiculously fast Wyrm works) a week-two weeks or so?
