OSCommerce STS Package

I am trying to install multiple contributions for an OSCommerce based site but am running into many roadblocks getting them all to work together - I am looking to have an OSCommerce system based on the STS and infoboxes to work with about 10-15 other contributions so far including options as images, ultimate seo or equivalent, optional related products, columned product listings, press release page, multiple product images, thumbnail generator and probably a few more. If someone already has a prefab solution that is already done thats fine or someone who is willing to customize it for me.
