I'm new to gardening. I bought some tomato plants and they're doing
well. Each was marked at a certain number of days such as 'Early Girl 80
Days'. What is 80 days? Does it mean the number of days from seed to
edible fruits or something else?

Well, sorta. Best use for this sort of information is "which of these
cultivars will ripen soonest?" in a relative sort of way, rather than
counting on the "days" thing to mean much. And yes, it's supposed to be
days from planting to harvest (first harvest in the case of things that
will keep producing for awhile) However, in the real world, the actual
number of days to harvest will be strongly dependent on air and soil
temperatures and amount of sunlight.

I saw no explanation of 'days' anywhere in the garden center where I
bought the plants. As a comment, I bought these plants which were about
as tall as my thumb in early June. Today they are up to my chin - or
about 165 cm. They are intermingled because I only planted them maybe 30
cm apart. I figure they are ok that close. Should I trim off the
branches which intrude on their neighbors?

I usually plant tomatoes about 30" on center, or about 75 cm apart,
with about a meter or 1.25 meters between rows. The closest I'd consider
planting the tomato cultivars you list is about 18", about 45 cm. apart
in the row, and that if the plants are trellised. They're really competing
pretty hard for sunlight and nutrients and water at such a close
spacing. No, I probably wouldn't trim, but try a wider spacing next
year. Bet you'll get more yield per plant.

What are your thoughts on topping tomatoes in arbors? I start pinching
off the meristems once the vine reaches the top of the arbor (cage). My
reasoning is that the vines would otherwise eventually flop back on
themselves blocking sun light to the lower part of the plant. Making it
a waste of energy that could have gone into the production of fruit.

Controlled growth vs uncontrolled growth.
