Google has wised up to internet writers and marketers creating lots of backlinks to try and improve their search ranking, and so focusing a lot on creating backlinks may backfire on you.
To promote your hubs I would concentrate on choosing good topics that people are searching for, a keyword rich title and not do too much else.
I would however create links between your hubs, both within hubs and also grouping your hubs. Social sharing is good for boosting your traffic too.
I'm not saying don't do backlinks - if you can get links to your articles on prominent websites all the better, and many websites will give a direct boost to your traffic from people clicking on links. Just don't go after backlinks just for SEO as it may cause you more problems that it's worth. There's a long thread in the forums somewhere from hubpages admin strongly warning against dodgy backlinking.
