Angel Food Wall 

There's a trail which comes out of the descent gully and skirts basically the base of the crag - so it's doable to leave packs etc. at a convenient spot before the start of the climb.

To descend, yes, there is a rappel/ downclimb if you enter into the gully up high. However, for Tunnel Vision you can easily avoid this and also have a quicker/easier descent. At the top of the final listed pitch in the Handren Guidebook you end up on top of a pedestal with another pitch of vertical climbing above you. You can do this next 5th class pitch and end up getting over to the descent gully up high. However to get into the descent gully much lower down, don't go any higher than the top of the pedestal, but instead go across to the other side from where you came up and descend into a chimney/gully system starting 20' back. Follow this system for a couple of minutes and several hundred feet, then take a sharp right and make a narrow traverse (following cairns) on dark rock towards the right. This will spit you out much lower than the rappel in the gully. Follow cairns and the beaten trail down from here.
