Please advise on potential upgrades... 7.5.4 / MySQL

[nhouse]

Hello everyone and Happy New Year!

I need your advice to help me make an informed decision. I am struggling with the thought of updating Plesk from 7.5.3 to 7.5.4 because it is suppose to work faster and supposedly has a few more new features I am interested in. Also, I tried to install a new set of PHP scripts the other day and found out that I need to upgrade MySQL to at least version 4. I read in a post somewhere that to do this you need to be running Plesk 7.5.4. If this is true then I might as well update Plesk.

Please review the list below of my present installation versions, etc. and tell me what I should be wary of. If you see something that I need to do to make this easier, please let me know. Ultimately I feel that more scripts will be designed to use the newer versions of PHP and MySQL, etc... so is it time to bite the bullet? I do appreciate your thoughts and expertise.
