I don't understand how to price my shop, I bought the gold account thinking I can auto price and I don't see how to do that either. And how do I change the what my doll looks like it's gross.

Shops have changed over to a new and very limited system. There's a guide here:

Thanks karen.

To change your HA's appearance, go to the Wardrobe, find the "Skins" tab, click the "remove my skin" link near the top, then save it.

Thanks jim.

How do I quick stock items in my inventory?

If you open the "commerce" menu at the top and hover over "your shops", it should have a "(qs)" next to the shop name you can click on.

However, you probably missed the shop revamp while you were gone and might need to deal with that, so you may want to check out the thread. New Shop Guides

Done and done, thanks.
