As things stand right now I would say that you virtually have no chance.
Winning 2 playoff games and then a playoff series on the road is a nearly an impossible task UNLESS you have by far the best team in the league. But you don't. You have decent starters, a weak bench with terrible game shape including one injured guy who is going to return with terrible gameshape just in time for the playoffs. That's why finishing in 1st place is so important.
Now if you have the cash to go out an buy a couple of studs and carry their salaries for several weeks without losing your shirt, then you would have a chance. But remember, other teams that would have home court advantage over you might do the exact same thing so that's always a very risky play.
