The only thing you will need to do is top off the cooling system and bleed out any air. With the cap off of the resorvoir you will fill up the cooling system. Start and run the vehicle leaving the cap off. This will force out the air. You will also find the upper radiator hose and press down on it forcing the air to come through. Once all of the air is out you will put the cap on and everything will be golden.
waa m97b44-d this is the type your vehicle takes but you can use a 50/50 mixture of prestone. Now the only thing you can do is use a jb weld type product and try and get it back together. If not you will have to replace the entire reservoir. I have done it for customers in a bind before. Make sure you buy the stuff that sets good with plastic and it should do the trick.
