In need of climbing input

I would need a climbing route in Yosemite National Park doable for someone who's used to climb in halls and now would start serious climbing (with hooks and ropes) partnered with a very experienced climber. Anyone having any suggestions?

(I googled but as I don't really understand how these things are rated, I'd love to get some input from people with know-how. Also, it's only a side detail so it doesn't need to be super expert know-how - just enough that climbers won't run away screaming *G*)
