Dependency Problems

Hello. I'm new to linux and I'm having some problems installing programs with apt-get.

Here's the outputs of me floundering around. I'm assuming I need to install programs that these other ones are dependent on. Is that the root of this problem? If not please explain, if yes please help me to know what commands I should use to get those programs.

Thanks Ubuntu community for helping me through all this adjustment.

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 googleearth : Depends: libfreeimage3 but it is not going to be installed
               Depends: lsb-core
               Depends: ia32-libs-gtk
 xchat : Depends: libsexy2 (>= 0.1.8) but it is not going to be installed
         Depends: xchat-common (= 2.8.8-3ubuntu15) but it is not going to be installed
         Recommends: tcl8.5 (>= 8.5.0) but it is not going to be installed
