I use Red Sea Pro tests for Alk/Cal/Mag although I have heard nothing but great things about the Hanna checker for Alk. I actually just use a Trident now so I haven't bothered getting the Hanna checker. The only other things I test for are nitrate (Salifert) and phosphate (Hanna).
For dosing I use Randy's diy recipe and for alk I used baked baking soda and for calcium I just started using bulk calcium chloride from Bulk Reef Supply. I had been using prestone driveway heat for calcium but it was leaving this pink goo in my dosing container that made me a little nervous.
Dosing by hand isn't hard just add however much of each solution that you need to a high flow area daily (just don't add both at the same time). I would personally look into dosing pumps, even the cheap kamoer pumps work well and are less tedious than doing it by hand. For instance I now go a month without having to do anything with dosing and even then it's just filling up the containers.
I keep alk around 8, calcium around 450, and magnesium stays around 1350 (my AWC I guess is enough to replenish it since I never dose it).
The worst part of dosing is figuring out what amount you need to dose and that isn't that bad. Either measure for several days to see how much it's dropping, or just start by dosing a small amount and wait a few days to see where the levels stabilize at. If too low add a little more to your dosage. The key in the beginning is testing a lot.
