So the combo packages are good...the ones that contain separate components but come in a single order? Would anything need added to this to get started? I understand depending on how my plants react I may need to add or subtract accordingly, but is this a good way to get started?

The product in your link is "all in one package." Assuming that just means it arrives at your door in one package, but each fert is in a different bag, then you are good. However, it might mean that all those listed weights of ferts are literally in one package (bag). Doesn't seem likely, but worth checking out nonetheless.
If you acquired a package of those ferts, potassium nitrate, potassium phosphate, micros complex, as well as potassium sulfate, you should be well on your way. The latter fert is not always needed as all it does is supply potassium and that is typically satisfied with the first two. Not bad to have around though.
Some people also use gH booster, but I don't have any experience with that so I don't know the best route with that. Lastly you gotta check up on EI dosing. I noticed there was a link for it there on the bottom of your ordering page. (Estimative Index) Read that thoroughly and use that, SOOO easy.
