Poly count reduction:
1. Removing unneccessary mesh
2. Decimating mesh

Materials:
Merge them with CATS material combiner (if the materials have small textures that only cover one or two items)
(Re)bake textures - Use texture baking to bake new textures from the visual effect of the current ones. More useful for pushing other atlased UVs into a big one.
