There's a guidebook- Great or Classic climbs in Jtree 5.9 and under (i cant remember the exact name)- has good beta on all sorts of moderate climbs, and i believe it describes if a climb is accessible for TR.
One thing to keep in mind- lead climbing in Jtree is normal for most folks, so be sure to check the crag and have spotters before throwing down your rope on a climb. Any popular lines will be busy and have people wanting to get on them.
When I was first getting started in climbing this was a little crag that we frequented, pretty easy walk up with bolts to set a toprope. Its also got a few much more difficult climbs on it if you decide you want more of a challenge. www.mountainproject.com/v/pixie-rock/105720658
