Checking Checkboxes & setting filename

Question

Hi,
I am fairly new in creating acrobat forms and scripting.
And now I will create a form for a friend and would of course create as user friendly as possible.
The Scenario is:
I have a form which has totally 6 Checkboxes, 2 Textfields and 2 Buttons.
Now i want to realise the following tasks:
1.) If one of the Checkboxes 1 - 3 is selected, the other two are automaticly unchecked. Also, if Checkbox 3 is selected the Textfield 1 is required. The same should be with the Checkboxes 4 - 6 and Textfield 2.
2.) If the Textfield 1 is required it should be checked if the something is entered and the length is 6, 8 or 10.
3.) It should be not possible to overwrite the original file. The user should be prompted to save a copy when he clicks the save button at the toolbar or the button at the form. Also the filename should be suggested based on which checkboxes are selected.
In example: "Copy_ChkBx2_ChkBx4.pdf"
4.) I want also add an button to let the user directly the pdf via email. The filename whould be generated like in at 3.). I want also to add some text to the email and set the subject to the filename.
I don't know if all that is possible but it would be great when it is possible that somebody would show me how it is possible.
Many thanks for your help.

No, the hidden field is in a while loop, so value="<%= moduleBean.getModuleId() %>" is always different.
This <td> tag
<td><input type="hidden" name="checkbox" value="<%= moduleBean.getModuleId() %>"><input type="checkbox" name="checkbox1" value="<%= moduleBean.getModuleId() %>"></td>
is in the while loop.
Does it matter that the hidden field name, checkbox, is different from the checkbox name, checkbox1, that the user sees?
