I think all you need to do is put the command you want to run at the
end of the ssh line. That is, rather than

ssh host

and then putting the command on a separate line of the script, you use
something like

ssh host command

(schematically, at least--I don't know what other options you're
using). See man ssh for details.

I'm not sure what you're asking there, but I'm a terrible scripter
anyway so I bet someone else will give better help :-).
