In order to learn Spanish well, you'll need to devote a lot of time and energy to it. You'll need to get a book (or two), preferably with some audio help. I understand that there are online courses, but I don't know if they're any better than studying from a book with audio help.
If you know someone who speaks Spanish natively, they'll be able to help you say things correctly, but probably won't be able to explain the grammar. You can ask those questions here.
Look around the forums to see what others are asking. You'll stumble where we have.
There are no shortcuts. Plan on lots of time and patience.
