What are the procedures for unlikely event when you lost
communication with the ground? Is it better for astronauts and
cosmonauts to try to reach ISS manually or go to abort and land?
Back in the Apollo days, the astronauts would always have a "PAD" read up to them, hours or even days before any major manoeuvre. For any burn, the ground would read up to them the angles to point the ship, the precise timing and thrust setting (if appropriate). The astronauts would write this down on paper.
That way, if communication was lost, they would always be able to execute the velocity change well enough to carry on.
For present flights to the ISS in low earth orbit, they would launch with all of the required burns known in advance, and I guess they would be able to make their own way if necessary provided the launch went as planned.
(Note however, loss of communication is a different problem to the case of a vehicle spinning out of control, as is happening with the unmanned Progress vehicle.)
EDIT: "PAD", from http://www.hq.nasa.gov/alsj/apollo.glossary.html :
Preliminary Advisory Data: the crew had pre-printed forms on which
they could write lift-off times and other data they would need in the
event that communications was lost with Houston. Before and after each
rest period, the CapCom would read up a list of lift-off times
covering the next 10 to 12 hours and, prior to launch, a longer list
of data was read up.
