If your colleagues are used to Eclipse, it's almost certainly best to
continue using Eclipse, with PyDev. Don't make a big deal of the tools,
just say that many Pythonista don't use a heavy IDE, mention PyDev, and,
if you want to, recommend pyCharm.

Don't overemphasize this. Those functions can be very useful, and using
them can lead to very concise and simple code, but (big BUT) more often
than not, they're overly cryptic when compared to list comprehension and
Do make a huge case for generator expressions/list comprehension, and

Speaking of testing: introduce them to the doctest module.

If using Jython is an option, present it! Jython will allow Java
programmers to use their existing knowledge of the Java standard library.
Explain, and make the case for, duck typing.
While actual functional programming is, as I said, a bit "out there"
from a Java/VBA standpoint, do show off function objects.
If you know what they're going to do with Python, you should point them
to relevant libraries/modules.
