Answer 1

You can't do this out of the box.
If you're able to customize code for the instance, you need to look into the Sitecore.Pipelines.HttpRequest.AliasResolver processor in the httpRequestBegin pipeline.
Override that processor to add logic for resolving regular expressions in aliases.

If you cannot customize any code, you can look into some modules that are available.

301 Redirect module
This one seems to support regular expressions.

URL Rewriter
This one is released by me, but doesn't support regular expressions.

And of course there is always the IIS URL Rewrite feature, but that lacks the ability to manage it from Sitecore.
