One of the live wires should go into the squigly line, the other into L1.
Both of the neutrals should go together into a bit of connector block.
I'm assuming you have 2 cables going to the spur; one for each light, and they are both switched independently, in which case you don't need both switches and fittings for either one to work on it's own.
If you are in any doubt you should get a competent electrician to have a look.
