Alireza, These questions are so broad that it's hard to answer.
If you want to be able to get all of your different nodes back from a single query, then they must all be in the same RTree layer (accessed through a spatial index in Cypher). If different kinds or subsets of spatial nodes are to be queried separately, then you need a different layer (and thus different spatial index for Cypher-based queries) for each separate type or subset. It also depends on the type of geometry you are using. There are three types of geometries - WKB, WKT, and simple point, and you cannot mix these within a layer. As for "normal" indexes, it all depends on what you are trying to do. I can't answer this question, except to say that indexing (some of which is done transparently if you are using labels) will generally increase performance.
