There is a package that comes with Mathematic that will probably
do what you need. Specifically, doing

<<Utilities`CleanSlate`

at the start of a session will load the package. Then at some
later time in the session you can simply do

CleanSlate[]

which will cause the will clear everything out that was created
*after* the CleanSlate package was loaded. I find this so handy
that I have the following lines at the end of my init.m file

<<PacletManager`;
<<Utilities`CleanSlate`;
SetOptions[CleanSlate,Verbose->False];

I explicitly load the PacletManager since I found in version 6
it loaded after every thing in my init.m file executed. As a
consequence, omitting this meant everytime I did CleanSlate[],
the paclet manager got zapped and I lost that functionality. I
do not know if this is still an issue with version 7 or not
since I've not tried omitting the line that explicitly loads the
paclet manager from my init.m file since using version 7.
