First - the best way is to install premakeready packages from repositories (via Synaptic, Add/Remove etc.) - there are thousnads applications - everythink you need...

Other ways are:

Using DEB packages which are not in repositories - installing is easy (doubleclick), uninstalling via commandline using 'sudo dpkg -r package_name'.

Using binary files/instalators (.bin, .run, .sh) - installing is also easy (doubleclick or via commandline using 'sudo sh ./file.run'), uninstalling is not too easy, but majority of these installators have also uninstallator.

Compiling - it's too long and complicated, so only links:

Lets do a breif overview to answer your questions, then you can drill down futher if you want.

1.) synaptic is just a front end for the dpkg package manager, in the same way apt-get (the command line interface) is.
2.) the contents that are installed via synaptic are pre-compiled packages created for the same target architechture, distribution and versions as your own.
3.) To compile a program for a different architechture on your current architecture you need to use a technique called "cross-compiling" this basiclly creates a tool chain compatible with your target architechture for you to compile against. This a fairly advanced and wide topic and should only really be done by people who understand the process, the software they are building current and target architecthure.
Packing up software for a different arch is a different matter, you can make your own "deb" file for a different arch quite was as long as you have access to the files to put in the deb and understand the packaging process.
