Any specific order to correct chemistry?

I kept up with chlorine and pH over the winter in my pool, but it has been just too cold to run the whole gamut of TF-100 over the winter. Just finally started to get a couple warm days together.

TA is 30
CH is 100
CYA is 50

Everything else is okay.

Can I add bicarbonate, calcium carbonate, and CYA all at the same time, or should I do one at a time?

If one at a time, which first?
