The Stat and Oring ( make sure you get one )and a gallon of Honda/Prestone Extended life/any antifrze without silicates is all... add about 1 hr and all done.
The thermostat replace is a fairly simple job.. the front cowels come off, the radiator ( held by 2 bolts,wire clips on fans ( first drain fluid form bottom hose)), the rear support bracket ( 2 bolts) and there it is. 2 bolts remove the cover, clean all , put in new o-ring and stat (stat weep hole on top ) , put all together.
While there check the hose clamps to the stat housing and tighten if needed. (( clean out side overflow bottle if want to do 100% )).
I wonldn't do hoses and esp wouldn't do w pump as failure rates are low
