Hi,
Tell me, what kind of load on the site gives p8pbb bridge?
there is support for Russian language p8pbb bridge?
have any discount p8pbb bridge?

p8pbb bridge doesn't have own database tables, so the its own impact is minimum.
But note that actually both phpBB and Joomla are loaded at once.
Russian language is possible for contacting our Support Center, there is no russian language pack.
Discounts are available for users who bought 2+ extensions:
Second or third license of the same product - 20% discount!
Customers who have > 3 orders get all next licenses with 30% discount!
Only active (not expired) orders are counted.

will p8pbb bridge work with the framework ja t3? http://t3.joomlart.com/documentation.html

Yes, it will work.

may be have a test site with access to the back-End joomla?

Sorry, this is not possible.
Please contact our Support if you need to know any special details.
