VPS - server help

Hi, I run my elgg off a2hostings Virtual Server. running kloxo.

 

I was wondering if anyone can tell me what is best for this, options I have are:::

apache or lighttpd

--------------

suphp or mod_php

--------------

several php config I can do, do not know which ones are best, and which ones I should not enable.

--------------

I seem to have an issue with ownership of files with some of these options.

--------------

 

I have asked previously for expert payed help but no one offered.

--------------

 

I hope I can find some help this time.
