If it works for you, use flashcards for amino acids!! You can probably use them for carbs and lipids too. Focus on getting amino acids down, understanding how pKas work, and figuring out how pKas influence each amino acid's behavior in acidic/basic conditions. When you get to it in your class, understand the oxygen-hemoglobin dissociation curve really well and the effects of changes in pH, temp, etc! (It's great MCAT material, and a big part of biochem is figuring out what IS important to study and what's minutiae.)
And as someone above mentioned, find diagrams that link all the metabolic cycles together. You'll notice that the products of one metabolic cycle are often the starting materials for another cycle. You'll want to study each cycle on its own first, but eventually, you want to put the puzzle pieces together and see everything in its entirety.
You'll likely have to memorize steps/products in the metabolic pathways. Use pneumonics-they'll save you!! Draw the pathways out on a whiteboard or paper too.
If you've made it through ochem, you'll manage biochem just fine.
