If it is your basics in OOPS that you wish to strengthen, Java is a good option(provided you know c++ or any other non-web-based language which supports OOPS). However, if you are looking towards web-development, Python should be your best option.
Yes, Python is a good option
Yes, Django is a very good web application framework(and they have awesome documentation and tutorials put up at their site)
To learn Python I definitely recommend reading "The Python Cookbook" cover-to-cover. Its fun, and covers some very important concepts. However, there really is no substitute for the standard python documentation. Its well written, but it might take a while through a major portion of it. Using it as just reference material is also a fine idea.
Well I have seen domains which allow Django to be hosted; also you should try out the GAE(google app engine) once you are comfortable with django. Its a great place to host your apps.
