As far as using other tools than those mentioned in Richard's list is concerned:
The list is basically a recommended list, chosen for reasons stated in the book itself (see the Chapter 7 description in Richard's posting above).
As far as RUP is concerned, I'd also refer you back to Richard's posting and to the book. RUP is part of the process, as is the choice of an implementation platform (app. server, IDE, etc.) but the whole concept of Convergent Architecture and Model Driven Architecture starts at a much higher level of abstraction... at the consideration of the architecture itself (not to be confused with an implementation technology - note the comparisons Richard makes in the book between IT architecture and classic architecture, as related to buildings). ArcStyler is the Architectural IDE which brings together other "best of breed" tools (much as an architect will bring together specialists such as electrical and heating engineers when conducting a building project) within an environment which enables you to implement and promote a specific architectural style from beginning to end.
A short word about ArcStyler support for other tools:
To use other application server platforms instead of those mentioned is, of course, supported by ArcStyler as the Architectural IDE platform. If your chosen implementation platform is a J2EE app. server, ArcStyler currently offers pure J2EE app. server support out-of-the-box. Specific vendor app. server support is delivered via MDA Cartridges which offer extended support for the more vendor-specific features in addition to the pure J2EE functionality. In addition to those already explicitly supported (and to the Java IDEs explicitly supported) further products will be supported with version 3.0 of ArcStyler...
A full technical briefing about ArcStyler and MDA is available on our web site and can answer a lot of these questions while putting RUP, etc. into context: http://www.io-software.com/products/as_media_main.html
