I think German grammar is kind of overwhelming - there are so many different rules to take into account in order to form a proper, correct sentence. How should I approach this problem?

I understand this feeling, as German is, compared to English, very complex. However, we will start building up your knowledge like a house. We will start with the basics - e.g., conjugation - and won't proceed until you feel totally confident in this certain area. You will see that as soon as we've achieved to put all this into a frame of better clarity, - which I like to support by graphics, catchy analogies and mnemonics - German grammar is nothing more than a set of rules anyone can learn by practicing.
