Yes, this is the way GPL works, you can create a new work based on
another work released under GPL , provided that your work is also
released as GPL.

you should just leave copyright notice and add yours listing your modifications.

The validation is really basic and automatic, it's a software
procedure which controls that the plugin has required metadata.

You maybe are talking about plugin approval. Currently a lot of people
can approve plugins, usually the approval is very fast but there are
no clear responsibilities between developers so it might happen that
your plugin passes under silence, if this  is the case, please
complain (loud) on this list.

You are not the first to complain but I thing that clicking on "Share
a plugin" and upload a single file (no other actions are required) is
not really complicated.
Of course you must be a registered user, for security reasons we
cannot accept anonymous uploads.

This is in the pipeline... feel free to implement it if you can, but
keep in mind that most developers do not read comments but read the
bug trackers.

I would say yes.

I cannot answer about the other questions, sorry.

Best Regards.
