Removing sliding glass door with stucco around it?

1time

My home has exterior stucco. I have an enclosed patio room next to my dining room with a sliding glass door in between. I removed the door to open up living space. One side of the opening is finished with stucco and covered with paneling. The other side is regular drywall. I want to trim around the opening but not sure of best way to cut stucco without breaking chunks out. Also, to finish the opening, should I glue corner bead to stucco rather than nail? I want to install drywall to cover framing but not sure of best way to blend in.

Got a picture?

Here are two pictures. A friend said I should have made a cut with an angle grinder before removing the frame. I'm thinking I should trim the stucco and drywall flush with the stud before applying drywall. What do you think about spray foam to fill in gaps and then trim smooth? I'm considering the rounded corner bead at edges or possibly molding on the stucco side since paneling ends 1/2" short of stud, which would bring it 1" short after drywall is installed. Drywall broke off flush with stud in a few places. As I'm sure you can tell, I'm a rookie at this.
What is your recommendation? Thanks in advance.
OK, let me try this again...

I created an album in the photo tab on this site titled "Wall opening".
Can't paste pictures into reply.
Ok, my pictures were too big. Let's try this.

Hard to tell from those small pics, but what I'd probably do is trim the interior of the opening with boards (1x6 or whatever the width is) and use casing trim on the walls on either side.
