Best plugins for a market place based on MU

I'm trying to build a hosting service on WPMU w/ eCommerce functionality [ via MarketPress ]. I'm curious what some more seasoned users suggest for getting this started && growing it in the future.

There are so many plugin options && it's a bit overwhelming. I'm looking for a Minimal Viable Product type of set up that will allow users to sell && to create affiliates [MarketPress + affiliates plugins should cover that, any good links would be appreciated tho].

If anyone has a list of plugins that play well together in a multisite eCommerce environment I could definitely use some guidance (:
