Masha ALLAH, very nice, good luck for the car, for the paint, try to get it done as precisely as you got the denting done, dont worry about little amount of money, that 'extra' piece of spent cash will give u smiles everytime u look at your car.
Regarding the engine, good luck with the engine overhaul, but, if u plan on swapping the engine, good luck in finding the cultus engine from the scrap market, also, the engine of Suzuki Swift Sedan 1990-1992 model is almost the same as that of cultus (carurettor version), so if u find that at a decent price, swap with that without any tension. Again, good luck and keep posting the updates about your car !
