I am new and really need to know something about installing the modules. Do I just upload them to mudules folder? and how to I view if they are installed right?
You upload the ubercart folder to sites/all/modules Once you upload them you have to go to the module list admin/modules and check the UC modules you want. After that in the admin section there will be a link to Store to set up your UC store.
Actually, it's probably "sites/all/modules". Also, you'll probably have to created the "modules" directory yourself.
There are directions about this in the documentation section of this Web site.
