Yes, a few tips here.
Like suzeeq says, you put 3 stitches on the cable needle [cn]. Then you move the needle + stitches behind your work. Knit the next 3 stitches from your regular needle, then knit the 3 stitches from the opposite side of your cn. [Here's a hint that may help: use a spread-out bobby pin for your cable needle. Then when you slip the 3 stitches from your needle onto the cn, use the wavy-tipped end of the bobby pin to slide the stitches on. Then when you knit the stitches off of the cn/bobby pin, you knit them off from the smooth-side tip of the bobby pin.]
Cables can be confusing, but they're tons of fun. Even your mistakes look impressive, often.
And once you get the hang of it, doing cables will quickly become second nature.
