As for apache, that's part of the game. The very first part of the readme mentions about "if you're not comfortable...".
It really is true, but is the most overlooked part of the readme, followed by the rest of it. Not to discourage you, but MU is an advanced server platform, and to support it really does call for a good foundation with PHP, MySQL, and of course Apache.
It really isn't recommended for a shared environment, as it will consume a lot of resources on a shared box, which in turn ticks off the host. Result: you wake up without a site one morning. Also, MU tends to violate their TOS. Either by resource usage, or the fact that you're giving out accounts to users. Not like user names, but accounts that can make their own site. Thus essentially, you're becoming the web host yourself.
