301 Redirects & Contact Form Fix Wordpress

1. I have recently switch my site to wordpress so for this reason structure of my urls are changed. I need someone to put 301 redirects on all my old urls through .htaccess and make sure that 301 redirect is added properly and tool here **[login to view URL]** shows the redirect properly. I have tried to do this with .htaccess and also with a plugin but maybe i am doing something wrong. Old urls has ".shtml ?n end while new urls are without ".sthml" rest of the structure is same. 2. I also want you to fix contact form on website as the website is transferred from html to wordpress so contact forms are not transferred properly. You need to create/fix contact forms and make sure they are working properly. I am using a contact form 7 plugin and also default contact form plugin come with my theme. The contact form needs to be fixed on 2 websites.
