Hmm, well the only way to get the links to not go to the free article site is to NOT link to the article directory site. If you'd like just the article to appear on your blog, I suggest you copy and paste the entire article into your actual blog post. This really is the only way to do it. You can't link to the article directory and expect the article to show up on a different page other than it's origin.
Remember you must include the authors resource box when you copy and paste an article into your blog. It's required in return for you to use the article.
As far as shortening your links, there are a few different methods. Are you using your own hosting company yet? You don't mention that or not. Since you are using a free blog like Blogger.com, you can use something like
http://www.tinyurl.com . You may also try
http://www.urlfreeze.com. Both of these will work fine for shortening your links.
If you have your own hosting account, I have a software which I distribute which allows you to quickly create redirect pages. This is especially helpful with protecting your affiliate commissions. It creates a quick page, and then you upload the redirect page to any one of your domains so the page is live.
You can download that for free here:

She offers it for free with her book, or she also offers it in The Honest Brands site to help people protect their affiliate commissions. But, to use this one you must be able to upload and install it on your own server. If you don't have experience at this, you might have a bit of trouble with it.
Nonetheless, If you are interested in getting that. You can download it here:

I hope that helps you. That pretty much covers all of the bases with all of the options I've provided you.
Take care,
