You are in the right place, but keep in mind we can't give you legal
advice. If you want that, you'll need to pay for your own lawyer.

You may do whatever you like as long as it is within the terms of the
Apache License. Providing a modified installer should be OK. I would
suggest you pay particular attention to sections 4 and 6 of the ALv2.

Making it degree branded should ensure you meet the requirements of
section 6.

As long as you provide credit in the form required by section 4, again
you should be fine.

When speaking to folks that are new to the ALv2 I usually use the
following example.

If I download Apache Tomcat, re-brand it as "Mark's Servlet
container", add a notice on the package that says "based on software
from the Apache Software Foundation" and stick the result on a web
site and start selling it for $1,000 / copy the ASF would be
absolutely fine with that. BTW, if any one wants a copy, let me know ;).

The key things are:
- don't abuse ASF trademarks
- include the NOTICE & LICENSE file
- credit the ASF

Note: You should read the ALv2 for the full details.

Some work is starting on a Maven build for Tomcat trunk / 7. That
might help.

HTH,
