Placing the solr home (which is what the -s option controls) outside of
your Solr installation directory is a good idea, for exactly the reasons
you state.  That's a step that I recommend for almost all users. 
Changing the dataDir is a more advanced config option, one that has a
few pitfalls for inexperienced users, so it's not a good idea to mess
with it unless you completely understand it.

I think you're probably in good shape.  Good luck with your setup!
