New to STL

I've started using STL in C++ but am not much comfortable with it.Could somebody tell me some good source for STL. I wanted to implement a min heap in STL C++ for Dijkstra Algorithm.Could somebody provide me with some code.Since by default the implementation is a max heap when you call make_heap() on a vector.How should I change the compare function so that make_heap creates a min_heap? How does the use of STL features impact the time and memory of the program from the point of view of programming competitions?
