First let me say this you may go to a lot of work for nothing. I have refinished/ repaired many bows, I have not examined your bow to assess all the damage, from the pictures this is how I would proceede. I would clean the bow the gently sand the riser. then assess any further problems also remove the remaining grip material, same reason.
The limb tip is a real worry I would attempt to gently open the crack assess how far it is delaminated at that point I would make a new limb tip overlay from hardwood and phenolic sand the front of the limb tip to provide for glue adhesion, using smooth on epoxy work epoxy down into the crack put on the overlay clamp and heat. Then simply reshape the limb tip, this method has worked for me in the past.
You could flood the riser cracks with superglue to fix the wood in place. Then carefully sand and reinish the bow you may want to add a limb tip overlay to the bottom limb for appearence.
Once again you may do this and have the fix let go and you hard work is down the drain
.
YOU will get other advice on this site, also there are some very good people here that repair bows professionaly this is simply what has worked for me.
Best of luck
