Pearling typically refers to relatively static bubbles. You see it a lot
on stands of riccia.

O2 bubbles of any sort (static, streams, under leafs) are a function of
plant O2 production AND O2 concentration in the water. You may have lots
of O2 production, which is good, but not see many bubbles if you have a
high fish load.

Phil, I too can report good results with the Nutrafin system. So far
I have seen a lot of growth in my Vals, crypts, horwort, and anubias.
I don't think this system puts out enough Co2 for tanks above 30g or
so. I really like the diffuser and will probably use it to attach to
a 2 liter DIY system. Considering that I only paid $19.00 for the
entire system, I would recommend it for the diffuser alone. I have
been running this system for about 2 weeks and have definitely noticed
a difference in the plant growth. I have also noticed that the Co2
production has already slowed down quite a bit from the Nutrafin
container(its not very big).

By the way, can anyone recommend a pressurized Co2 system - brand,
price, dealer?

Plant respiration occurs on the underside of leaves, so yes, it can and does
occur there. With small-leaved plants like Riccia, the bubbles are much
more visible.

Do you think the diffuser would be ok to use on a pressurized system?

Yep, pearling it is.
