Default hi LTspice about!!!

Hi,Everyone,
I am a Final Year Student having a project of powe r amplifier Class B, named Blameless by Dougles self. I new to the LTSpice and now i requested to use the LTSpice Software to simulate the circuit. but unfortunately there did not have the Model Transistor BC 550 ,BC 560 , MJE15030, BD 139, MJE 15031.. all these types of transistor. BY simulating, i using the model in the LTspice Lib given which is nearly to the expected Vceo and Ic that I need.
I found this
More LTSpice models

and I followed the instruction to import but still cant work it out.
Could anyone give me some advice on how to do it.

Further more, I having the problem to simulate out the DC graph, AC graph and transient graph for the Class B Blameless Amplifier.
