Bro first of all, its no big deal. dont worry too much. its a small hit. bumpers are usually not counted in painted parts. Plus, think of it as sadqa paid. ALLAH nay kisi baray nuksan say bacha lia.
Now, coming to the issue. DONT get the bumper replaced. you will be wasting a lot of cash if u do.trust me, i ve repaired bumpers with much more damage then this n they turn out to be excellent if the painter is good. the dent will be out easily, the top portion might have to be heated a bit to bring back to original position. n thats hardly a 5 mins job for a gud bumper repair guy.
Next up, get it repainted preferably from Honda 3S. it would cost u more but its always worth the price paid as its a brand new car. tell the denter to keep the puteen layer as thin as possible. otherwise it cracks very soon.
as for the small dent on the boot lid, u can get it dry dented. no paint will be done on the area. ask ur friends or anyone for a well reputed denter who specializes in dry denting. n u ll never even believe the dent ever existed!
P.S. Invest in a rear view camera
