'Into the blue' is an early CC DWS to to Swanage- Conner Cove (Fisherman's Ledge etc.), it's in Dorset, so doesn't include Devon.
Rockfax's 'Deep Water' has a good section on DWS on the South Devon Coast- make sure you do White Rhino Tea at Berry Head- it's class!
Re: Anstey's, Cordee's 'South Devon and Dartmoor' has Ansteys in it, although it's old (1995) it still covers Ansteys well. There's a supplement that also covers the DWS developments on the coast, though IMO I think the Rockfax guide is clearer for that.
