I wanted to know if the process of shifting from blogger to wordpress is easy or difficult? We just have to use the import feature in WP..isn't it??? Will it effect SEO? I use a custom dot com domain on blogger.com
Just use the Blogger import feature and you should be good. SEO shouldn't be affected since you're using a custom domain name which I suspect you will be using for your WordPress site. Just make sure you use the same permalink structure.
