Zencart Modules & FTP Work

I need two modules installing another module that needs to be configured. (all in zencart) + a line of google code adding to a joomla based website [login to view URL] & I would like a module that would allow me to batch print customer invoices.(every three months I have to print hundreds for my accountant) & I need to change prices for lots of products in one go. I have a wholesale module installed and think it may be easier to change the prices on a spread sheet then upload them. ( I need some instruction on this) & I have banner manager installed under the tools section in the admin area. I would like some help configuring this section. I need to upload banners here and turn it on and off on the homepage? ( I need some instruction on this) Finially I need a line of code supplied by Google to be added to the ftp files of a joomla website (this is to verify an gmail business address)
