While that site is great and you can learn a lot from it, it's not the end all be all for ribs.
If you're going for baby backs, remove the membrane from the back and then put a light coating of worcestershire on both sides. Rub to coat ribs and then apply your rub of choice to both sides. Then, apply an even layer (not too thick) of brown sugar on the meat side only. Smoke around 275 (I prefer pecan for these) for 5-6 hours until probe tender. Once tender, start brushing on Sweet Baby Rays honey-chipotle in a thin layer. Reapply sauce 3-4 more times over the course of about 30 minutes until it gets nice and tacky. Slice them bad boys up and enjoy some amazing ribs.


For spares, apply the same coating of worcestershire to both sides and then your rub of choice. Smoke them as well at 275 (I like to use hickory and oak for spares) for 5-6 hours until probe tender and then enjoy. I don't sauce spares.


Also, for a rub that you can buy at the store, I really like Meyers Texas BBQ Rub. It's a good blend that can be used on brisket, chicken, ribs or pork butt.
