Answer 1

There is two path which you can go in case of migrating.

1. Emulation Components . However there is a chance that some of the components wasn't added to emulation so you may get exceptions and this would be the place where you can add them and make pull requests to Royale. Those components allows you in best case successfully build your application without changing drastically UI part, but you may won't see anything on the screen or it may be messed, cause there wasn't volunteer who could work on displaying better them.
2. Another path is to distinguish your pure ActionScript code (no dependency to Flash) from UI part - pure AS3 code should ported without any problem - and rewrite UI from scratch using Basic module or Jewel

All libraries which you have mention have strong dependencies to Flash, so my recommendation is to find JS replacement for them and use it in your porting. There is also PureMVC which is working pretty good with Royale - it's has been tested in several applications already.
