Module development and code questions

First of all, i'm a beginner at Drupal. I have an issue. I accidently dropped my comments table in my DB. So I lost my comments module on my site. I can't comment on any blogs, images, forums, etc. How can I recover these tables? How can I get the comments module working again?? I already tried reinstalling the module, but no luck. Please help.

Thanks,
CH

Use case:

In a local community website, there is one calendar for exhibitions and another one for community events. Calendar contents should not overlap: exhibitions should not be displayed in community events calendar and vice-versa.

Both calendars have a direct link in the menu that opens the calendar view with today "selected".

Attempt to implement this:

I've installed and enabled the Event module, and created two different content types: exhibitions and communityevents. I've specified "Show in event calendar: Only in views for this type".

In the forms API can I override the default class for an element?

I wish to have right aligned inputs for numeric fields and I just can't find details on it.

thanks

I'm using Profile module to create user list. Currently it works great except that it lists the users based on the latest addition (so the first user always get pushed to the end / bottom of the list even if his/her first initial is "A" ). I also notice that it doesn't have paging option, so the list will never break to page 2,3,4 or more if the list gets too long.

So is there a module that can sort the list alphabetically and create paging?

I have some question. I'm writing my own module and i want that the users can comment content, and i saw comment module. Can i use it? How to make it? I'll be appreciate for any tip;)
