Definitely you will get some benefit.... but how much no one can say. You can also use google webmasters tools, there you can submit your new url in place of old url.
A portion of your pagerank will pass to the redirected page, but not the entire pagerank. marketingpilgrim.com/2010/03/google-confirms-301-redirects-result-in-pagerank-loss.html
