RRC does have the ability to import word documents into artifacts.  In RRC 4.0 you can import a word document into a single artifact and you can import a word document and have it parsed into multiple artifacts.  Also, you can import a word document into an artifact and use some simple editor actions to manually "break it up" into several artifacts.  Earlier versions of RRC have a subset of these capabilities.  I'd see if RRC's import capabilities are useful before looking at using the RQM import.

You can, in RQM, import a Word document as a Teat Case (which is roughly analagous to a Use Case).  It does require a bit of configuring to set this up and you need to describe the "structure" of the Word documents so that import can map what's found int he document to different attributes.  There is no direct way to turn a Test Case into an RRC artifact, but you can (if using RQM 4.0 and RRC 4.0) export test cases as csv files and import them into RRC.  I haven't tried doing this, but I believe this export/import will not carry through any rich text (I don't believe RQM will export the rich text content of the Test Case), but I could be wrong.
