I was under the impression that the link only appeared for those logged in as teachers and admins for the very reason you mention. Have you tested it loggged in as a student?

Maybe this has changed since I read about that, but if it has then I would suggest changing it back (i.e. making it only appear to teachers and admins) rather than deleting it completely.

If you want to optimize then you can reference (and pehaps add to ) the performance info in the wiki: http://docs.moodle.org/en/Performance

It's probably worth investigation to see if there is an actual problem above and beyond overloading since you'll probably need to do some profiling to figure out what the bottleneck is anyway (that is, if you're running out of RAM it would be silly to upgrade your processor or vice versa)

Yep that's true. See Bug #5727 for some more info and a couple of related issues.

I looked into this too and the only way is to use a javascript that identifies the table via a CSS id or classname and adds the appropriate CSS class to the alternating rows.

I've used this before to save time when creating and editing static HTML content and it works quite well.

I'd guess you've added new fields after the intial creation of the database. Try looking at the add entry template, hitting the reset template button and then saving. It should create something simple but effective, and for the entry screen at least you'll rarely want to do anything more complicated than what the default provides.
