yes, you can walk around & down to the tree ledge in the middle of the cliff. beginners may find it useful to rope up before the slab at the start of the traverse on the ledge over to the Barber Wall area, tho most people do not. then there is the tricky little spot just before you get to the Upper Refuse area that many people, certainly all guided parties, rope up for. then you are all set for Upper Refuse which may be the perfect place on Cathedral for a beginning leader.
RE Toe Crack: I should have mentioned that in order to get to Toe Crack you have to climb one of the starts to Standard Route.
1) the direct start is actually pretty stout. you climb the dike past a pin. that's easy enough. however from there you have to step left into a flaring crack where it's a tricky gear placement that never feels all that solid to me, and is often damp.
2) I usually do the alternate start to Standard on the left, going up the right-leaning ramp to under Turner's Flake. you have to step down and make an awkward step-across to the base of Toe Crack. many find this a bit on the scary side, tho with good gear and double ropes it is pretty safe.
as is often the case at Cathedral, the first pitch of things is the "gotcha".

Final Gesture... it's been a couple of years since I've done this, but I don't remember it as "overhanging". there is the balancy move onto the buttress, then you move up the the block and then layback & wallow onto the top of the block.
