welcome to the debian list. using michaels well working packages, 
typo3-installation is as simple as it could be.

since noexec is _not_ preventing files in /tmp from being executed, this 
option is not keeping it's promises. there has been an interesting 
thread about that in comp.os.linux.security. the most helpful posting is:

hm. the only thing i can tell you for sure is: turning off swap and 
limiting your system will keep it performant. i don't think that 4 GB of 
swap space helps. operations (or data) being swaped to harddisk are 
running much slower - no matter if 1 or 4 GB swapspace. if traffic's too 
high, increase your RAM or balance your load instead.
