With the current version, you should be able to document the table by editing the description. This description will appear just below the table name & breadcrumbs, but above the properties. This description will also appear on the list of tables page. Most objects can be documented this way, by using extended properties.
The hidding of SQL Script, I have put in something into the upcoming version that will stop the SQL Script (& link) from being outputted, however there will be no UI to support this feature, but it should cover what you want.
Regarding time frame, I was hoping to have this point release out by January 2007 sometime. Hope that helps.
