Quick question, is there supposed to be 2 gaskets under the master cylinder or just one. Like one either side of the steel bit?

If I'm carrying on like a pork-chop, I'm having a great time.

If I go very quiet there's a very good chance I broke something.

There is only one paper gasket and it goes on top of the plate between the plate and the master cylinders.
The gasket under the plate is a different gasket and IIRC it is a black foam plastic material.
It's the same gasket that goes under the LHS plate the heater hoses pass through.

Some clutch master cylinders also have an additional metal plate that goes on top of the bottom plate.
If you have clutch release travel problems removing this plate can sometimes help.

I've always found it to be the other way round? If it's missing this lowers the pedal travel available.........................

It depends on what type of master cylinder you have.
The cylinder push rod assemblies for metal and plastic tank master cylinders are different and not interchangeable.
I found this out when I fitted a Lockheed/PBR type plastic tank brake master cylinder to my S which originally had the large metal tank master cylinder and ended up with large pedal travel before anything happened.
The later plastic tank master cylinders had a weird piston and push rod assembly.
This used a longer pushrod than the earlier metal tank cylinders as the later cylinders didn't have the spacer washer on the push rod assembly.
The push rod had to be longer to get the piston seal position as close as close as possible to the compensating port.
Without the longer pushrod assembly the piston was at the bottom of the cylinder and not in the correct position within the cylinder.
The extra metal spacer was part of this arrangement and for clutch master cylinders this was often removed to get increased clutch travel.
