Web Services will form the core of the integration strategy - based on a Service Oriented Architecture.
To provide guaranteed message delivery, I'm looking at possibly leveraging one or more of the following:
One possible tool to leverage to help flatten the learning curve for the .NET developers on the team: Apache NMS project, the .Net Messaging API.
This of course creates quite a challenge for the day-to-day operational management of the message queue infrastructure.
One possible monitoring solution that came up during some research is Hyperic HQ: The Complete Systems Management
Another candidate for monitoring the JMS infrastructure: HermesJMS
HermesJMS is an extensible console that helps you interact with JMS providers making it easy to browse or seach queues and topics, copy messages around and delete them. It fully integrates with JNDI letting you discover administered objects stored, create JMS sessions from the connection factories and use any destinations found. Many providers include a plugin that uses the native API to do non-JMS things like getting queue depths (and other statistics) or finding queue and topic names.
To add to the complexity stew, we have Microsoft BizTalk 2006 R2 selected as a core component of the solution architecture, as well as IONA Artix 5.1.
In doing some research on the message queue integration topic, I've come across the following web resources that could be useful to others:

JMS Adapters for .NET & BizTalk
JNBridge JMS Adapter for BizTalk Server - (km: but at their quoted price of $$9,950 seems excessive).
BizTalk Utilities (tutorials) currently includes six different adapters including Databases, Messaging, SAP, SOA Accelerator, XMS and a Legacy Adapter. They work with all Microsoft BizTalk Server versions (2006, 2004, 2002) and editions (Enterprise, Standard and Partner). (km: pricing is MUCH more reasonble between $500-$4,000).
J-Integra® Interoperability Solutions
J-Integra® Interoperability Product Suite currently consists of: J-Integra® for COM (Java/COM), J-Integra® for Exchange (Java/Exchange), J-Integra® Espresso (Java/CORBA/.NET), and J-Integra® for .NET (Java/.NET).

I will need to begin writing some admin scripts to manage some of the operational aspects of the Enterprise Architecture / SOA that I'm buliding, and my plan is to first look at Groovy as a tool to help with those tasks:
For future reference, I found a Python Mini-Learning Guide on the The ServerSide Interoperability Blog.
