Replace slider handle and multi-point mortise lock

Question

There is a sticker on my door with '5800' listed which brought me to your website.
Door: 1 5/8" thickHandle/Face plate: 9 3/4" x 1"Lock/latch: 11 3/4" x 3/4" (looks like 82-265)Strike: 10 7/8" x 5/8" (looks like 82-249)
I would like to replace the handle and multi-point lock with face plate. Will handle 82-086 and lock 82-265 be a direct replacement? If the existing strike has the same dimensions as 82-249, does it need to be replaced to be sure it matches with the new lock/latch?
What if anything do I need to confirm on my existing door to make sure 82-806 will work as a direct replacement?
Thanks!-Tom

Hey Tom. Good job with all this--I agree, the 82-086 Handle Set and 82-265 Mortise Lock match your old hardware. If your old mortise lock is identical to the 82-249, there shouldn't be a need for the new keeper. Let us know if you have further questions.
