Module development and code questions

I would like to implement a time schedule for a small number of employees. I wonder before starting to work on this if there is a module with the functionality to schedule and track hours worked by an employee, if there is no specific module, I will appreciate if you can point me to a module that could be used as a base for this kind of job.

My problem is two fold

First I want to understand where the check for field label resides. Say I am using a date field and after choosing "select (drop down) wizard" for date, it asks for a "label" i assume its a widget label. Now what I want to do is make that label textfield not required and give it for user to fill.

Okay, so I have created a custom content type. Rather than redirecting to "node/node id" after you create a node, I need to make it redirect to another location, but I still need to include include the node id in the new redirect location.

The following attempts didn't work because the hooks are called before the node is actually created and assigned an id.

I've looked over previous posts on this subject and I can't come up with a concrete answer to my problem. Can anyone help?? I really need some kind of chatroom on my site. What is the best way to create one?? I tried the chatroom module and I get all kinds of error messages. I also attempted the phpFreeChat and nothing opens after I install. I hear there is a way to fix the errors inside the chatroom module...how do I go about correcting these errors? Let me remind you I'm a beginner at DBA. I'm controlling my DBs through phpAdmin. How do I correct the lines through phpAdmin?
