You can always destroy your system when modifying system files, but on the other hand quite often we have to in order to configure it the way we want. Besides: No risk, no fun!

General advice: ALWAYS make a backup of the file you are about to mess around with [I had to learn that the hard way for a few times x-(]
A quick way to do that, make a copy of the file in the same directory and append it with a suffix of your liking:

Example:
# cp /etc/apt/sources.list{,-OLD}

This command creates a copy of the file and appends '-OLD' to the copy. So in case anything gets screwed up (network-interfaces, fstab, mtab, sources.list, you name it) you copy back the original.

As far as I know, Synaptic is just a graphical frontend for apt-get, the other package-management tool for Debian-based distributions.

You know that you do not have to use ncurses interface of aptitude but may simply type commands as with apt-get like?

aptitude install PACKAGE
aptitude search PACKAGE
aptitude update && aptitude upgrade

I hope that makes things a little bit clearer,
