When things dissolve in water eg salt they fit in between the spaces between the water molecules, correct?
so would a liquid with a lower density than water allow more dissolution of the same substance eg salt?
And does it have to be liquid? whats the reason for why a low density wood is a bad solvent. I know its a stupid question but i cant get the answer!

No, not just density, the actual answer lies in the chemical nature of the solvent. Water is a polar compound and can bond well with a lot of materials. Any thing that can bond better than water will be a better solvent.

Good Question.
I'm not sure about the answer to the first part of the question. But if it has to dissolve salt, i suppose it would have to be a polar solvent.
I think the reason why low density solids can't be good solvents is that the molecules of the solid can't "flow" away to make space for the solute molecules.
