In the case of your house there is no real effective way to bond to the house. Don't worry about the house or foundation.
Do bond the gutter downspouts if they are metal.
Exposing the rebar in the slab will be difficult and messy. Use a diamond saw to get a clean cut and chip out between saw cuts. You will see the area you have worked on. It will be very hard if not impossible to hide the areas you cut out. So think very carefully about how it will look when you are done.
Typically there is at least 2-4 inches of concrete on all sides of the rebar so you will have to go into the slab quite a bit.
