I'm not an A/C guy......HELP!

Help! The A/C compressor in my daughters 96 Intrepid apparently locked-up and burnt the belt off. I'll put a new compressor/clutch assembly on. I'll go ahead an replace the receiver-drier/accumulator (which-ever one it is). Do I need to replace anything else? Does this model have an orifice tube or expansion valve and where is it? Is flushing the system necessary?
