alignment problem of new fields added

1.is the submit form be moved to the bottom of the discussion .in my cases 90 percentage of the visitors will be there to read the comments and reply . only 10 percent will be open up to starting a new thread .
2. another way is to make the part a 2 coloumn and make the form to the right part .(in my site iam using a seperate tab for review which looks like a whole page ).is this possible .?
3.1 or 2 is a must for me .is there any way to change it in settings or by simple customization ?
4.i have added some more fields in the form . one of them is title for the review . i want the results of those fields to be come above the comment .the title of the review coming after review is not looking good .is it possible?
i exactly want this way . the name /username should come below the profile picture/avatar and below that the user role. and in the comment section the title should come where noe username is there (dont want the term title to be specified). and the other fields should come below as of how it comes now and below that only the comment section should come.
5. i have added a field ‘mode of transportation’ with multi select options . but the field name is now coming after the options . its looking weird .this is the url where i have implemented it .please do check.
