Having a tough time finding the part numbers to purchase. Mine are starting to balloon and do not want these erupting.

Any help is greatly appreciated!

Are you talking about the pair going into the firewall?  If so, they are for the heater core.  They should be available at any parts store (might need to order them).  Best practice - cut the old ones off the heater core nipples with a box knife.  If you try to break them loose normally, you will probably bend or collapse the soft aluminum pipes to the core and you do NOT want to be stuck replacing that...

A few weeks ago my local Mazda dealer identified 6 coolant hoses for me, of which 5 were available from Mazda, which I bought from them and one was discontinued (the lower radiator hose.)  The discontinued one is available as aftermarket, see a thread about this from a couple of days ago.

I later learned that there are actually a total of 8 hoses and not 6 (two for the oil cooler), but I know at least 5 of them are easily available from Mazda.

Which hose are you looking for, and have you talked to a dealer?

Replacing the radiator is next for me, so I was thinking about refreshing all of the coolant hoses at the same time.  The only one that looks to be in bad shape is the lower radiator hose.  110k miles and 12 years can really mess with rubber parts.

I just finished a clutch install, and noticed a smaller hose routed behind the block.  Maybe that is one of the hoses your were referring to?

Those are the heater core hoses and as Mark already told you do not remove them by pulling them.  Remove the clamps and cut the hoses off the piping and peel them off.

Here they are

Bought these two (among others) from a dealer a few weeks ago and have already installed them.
