Is there any way to display the check boxes I have added into a form in two columns rather than just a single list? Also my site has added bullet points beside each check box and altered the text alignment as shown here: http://greenbuyerguide.co.uk/business-registration-form/
Can this be fixed?
Yes and Yes. If you're using the 1.5 release candidate version, you can take advantage of the new "ready classes" that will allow you to create 2,3 & 4 column checkbox lists. You can download the 1.5 RC version from the downloads page if you want to get started with it. You can find more information about the "Ready Classes" and how to implement them at the URL below.

You can add this to the end of your theme stylesheet and it should override the bullets in your form list.
body .gform_wrapper ul,
body .gform_wrapper li,
body .gform_wrapper form li,
body .gform_wrapper form ul li { list-style-type:none!important; list-style-image:none!important; background-image:none!important }
