Position elements inside form field

Hello - I'm in need of assistance positioning elements inside the form body. See form above map: http://184.173.196.201/~hostccl/property/townhouse-condo/. So I have an issue with positioning the input fields and copy - would like them all indented 11px from left. And would also like to be able to control the vertical size of the tan field so that is looks something like this: http://184.173.196.201/~hostccl/wp-content/uploads/2013/03/form.jpg. There will be several of these forms which all will be specific to a certain property - so there will be a different form ID for each - so the styling will need to be form ID specific. I was able to locate the code for most of this - but it seems to be all over the place. What I need to accomplish seems quite straightforward, but . . . Thanks, for you help. MM
