Thanks for the reply, but those options are not suitable either.
I need to be able to connect a standard (male), VGA monitor connector to the tablet as that is used on all projector/smart boards in schools for displaying a laptop on the screen. I would also like to be able to connect the speakers to the tablet using a standard 3.5mm jack, which is why I was looking at my option 2, as it has all the relevant connections that I need. I thought if I could connect it to the tablet using option 1 via the micro USB, I might have a solution.
I have seen a VGA to 30 pin connector, but it was for the iPad. I need something like this, but with a 3.5mm jack like my option 2.
