are you talking about the latest corolla GLI? if you are...i guess the holes might be there already cuz the SE Saloon comes with the side skirts and usually...the frames are all similar....but like i said..im guessing.
just get underneath the side of your car and see if u can see any holes. even if u dont have them....just drill and put them on...its simple.
putting skirts with any kind of glue sounds like a bad idea....lol...usually....with glue...they you dont get a 100% fit and if u dont...they will look like shyt.
