Yes you can get the Visa on the basis of these things even if at the end you do not go. I would suggest contacting some agent and getting a blocking "dummy" ticket for outward and inward travels. Those all letters will only be useful if the visa officer actually asks them. I sent my dad the invite letter but it was never asked. They had entire itinerary from the tour operator for their local US tour, that was never asked. Also I never gave any of my financials here to show I can "support" them here. They even took their assets information in India (own house, demat accounts with shares etc) to prove (if asked) that they fully intend to come back to India and only going for touring USA and attending a function.
I don't even know what that I-134 is.
They got Visa for 10 years.
