I would recommend the OEM/Aisin timing belt and water pump kit. That will come with everything you need. There is a member on ebay who sells them for a good price (Aircabinman I think) and it is an all-inclusive kit. While you're at it, you should replace the accessory belts as well as the tensioner pulley on the AC belt. Sounds to me like that's your cold start squealing issue if it isn't the belt itself. I had the same problem and that solved it.
Additionally, why didn't you just replace all the plugs at the same time? Seems that replacing 1 (albeit a very broken one) is just a band-aid.
