There are a handful of redirect addons in the marketplace. I recommend this one:

The best way that I can think of to redirect to a specific area on a page would be to create an anchored link. So, you do the following:

1. On the page where the redirect will forward to, click on the block that it will go to.
2. In the "Design" option, assign it a unique ID (eg. "#redirect"). Save / publish.
3. Then, add the redirect block as necessary, and enter the anchored link like so:http://www.mywebsite.com/somepage#redirect...

I hope that made sense and was helpful.
