GFCI combination switch and outlet to fully switched protected outlet
Couple things wrong in the diagram - you have 2 neutrals labeled going to the outlet for the disposal and 2 hots tied together. It should look like this:



The garbage disposal is on the right.  It's unclear from your diagram, but if there are other GFCI outlets downstream you would connect them to the load terminals on the bottom of your combo and tie the ground in with the rest of them.

One thing I would mention about the garbage disposal though - don't use a normal outlet for it, use a fused outlet like this one:



Ground fault only protects against shock hazards - fused outlets protect against motor stalling (i.e. it gets jammed). Most AC motors will not overload the circuit if they stall, especially a 20A kitchen branch. This will not only protect your motor if you drop silverware or something down the drain, but it is also required by code in many if not most areas.  Make sure you size the fuse appropriately for the motor (you'll likely find a fuse rating in the installation instructions for the disposal).
