PAC only list the 1519s for .625" max lift.
The PAC 1518s are also listed for .625" max lift, but in the comments section of 2012 catalog it says for up to .650" lift. (scroll down to pg 12 of pdf 2012 catalog under "LS Engine")

After reading the 1519 specs it looks to me that they would be good for .040" more lift than the 1518s.
IMO, I'd contact PAC to verify what the max lift is.

Depends on the installed height. I found that the stock setup doesn't come in at 1.800" but closer to 1.765". Not sure what coil bind is on those springs but you should measure the installation height and proceed from there.
