Yes. Assuming that you mean that the light is polarised at the source, rather than at the slits.

In fact, I think light will only interfere with light of the same polarisation.

Yes. Which can be a problem when you use a polarizing beam splitter, giving you orthogonal polarizations.

What happens if you split a polarised beam, rotate the polarization of one half (say by passing through sugar solution) and then recombine them?
Can they interfere?
