The rope trails down to the right of center on Jan...
The climb can run anywhere up the face of the rock. The quartz knobs are plentiful, but very slick and difficult to hold or stick a foot on.
Follow the Billy goat trail to the right and turn left at a small bridge (the approach trail is obvious). Making the left puts you at the base of the rock. Jane's Face is immediately after a chimney - it's not very far past the bridge/turn.
Natural anchors at the top. Several trees and flakes are available. You'll need 40-50 ft of fixed rope and 20-30 ft webbing for anchors.
