You pH is at least 8 and may be considerably higher. Keep testing and adding acid in small amounts (8oz. or less at a time) until you get the pH down to 7.2-7.8.

Don't worry about your alkalinity for now. Get the pH in line and then see what you alk is. It will probably actually go down some more as you lower pH but you don't want to try to adjust both at the same time. When it is time to adjust it, yes, you use baking soda to raise it. You may want to consider running a lower alk than is typically recommended if you see constant pH rise. Many SWG users report that problem and a lower alk will help combat that. There are several threads and posts by chemgeek on that issue over at poolforum.com.

What does your pool manufacturer say you should have for calcium? Most people think it doesn't matter in a fiberglass pool (and it probably doesn't) but your manufacturer may require something like 100 ppm or greater to maintain your warranty. If so, yes you can use calcium chloride to raise it.

It doesn't sound like you're doing the CYA test right. There is no color change in that test. You mix equal parts pool water and reagent, mix for thirty seconds, and then add it a little at a time to the test tube until you can't see the black dot at the bottom of the tube. You then read the CYA level from the side of the tube. If you haven't added any CYA don't bother testing for it because you don't have any. You can add pure CYA or you can chlorinate with tri-chlor or di-chlor until get the CYA to the level you want it.

Have you added any chlorine? If not, that's why your sample doesn't turn pink when you add the DPD powder. By the way, you only need to add two level scoops of the DPD powder. If it doesn't turn pink, go no further as you have no chlorine. If it does, add the R-0871 dropwise, swirling after each drop, until the sample turns clear. Multiply the number of drops time 0.5 (if you use the 10ml sample size) or 0.2 (if you use the 25 ml sample size) to get your free chlorine level.

Is the Autopilot running? If so, you should have some chlorine. Seek advice on that from whomever installed it (they should be responsible for getting it running initially) or post your question about it over at troublefreepool.com. One of the members over there, poolsean, is an autopilot employee and very helpful on all things SWG.

Good luck.
