Possible Title: 
Double-ING UpGood Ones:Pier gp.   ILA
Pay stub?   OLA 
Switch back?   EROO
Caesarean section?   VENI [tough one: it’s a section of the phrase with 
vidi and 
vinci]
Literary no-show   GODOT [love this one]
Theme: doubling of letters before –ing
Bit of surfing damage   BOARDDING

Who knew?:I didn’t know lots of them today: SEVE, NAS, DSL, NPRNEWS, TISH, LARGENT, ARLEEN, and KOH.  (Amazingly I knew LATOYA was Janice’s sister.)  I managed to do this in ink with no write-overs, due more to good puzzle construction than my skill. 
Some Nits to Pick:Like much rush hour traffic   STOPGO [the idiom is really “stop and go”]
