About 301 redirect

I bought several domains that have backlinks to them and I'm able to redirect any domains that I have through my control panel at my webhost to a specific website. But was wondering if this would also redirect all the links that are linking to the domains, and then redirect to the website? Or do I need to create a website for every domain that I bought, and then make a 301 redirect?

Absolutely it will redirect the link juice Just be aware though, that it's a double edged sword, because it will redirect the good with the bad... so check the link profile carefully, and check for penalties first too...

Yes it's probably the easiest way and will pass the link juice, just make sure they arn't all spammy.
