You'll probably pay 8-9$ per lb, maybe more for wet, cycled ready to use rock. it depends on the store.
Now that I'm home and can have a proper look at the bottles you have:
1. Seachem Reef Complete - for calcium. Keep it, but you have no need to worry about calcium right now.
2. API marine quick start - Yes. Ammonia detoxyfier, which is what you definitely need especially in the absence of an ammonia test kit. Also claims to be a bacteria additive, though I've never heard of anyone using it. Not sure if it messes with ammonia tests. The API ammonia test it most likely to be compatible, but it is known to give false positives at low levels. API has a terrible reputation for test accuracy, but is better than strips.
3. Fritz complete - does the same thing as the API stuff. May give a false positive or negative ammonia reading depending on the type of test.
4. Fluval cycle is a bacteria additive, which is what you need. I've never used it.
5. pH increase - toss it, like I mentioned above, you never want to use magical pH manupilation products, they mess with the stability of the water chemistry.
