Module development and code questions

My organization is hosting a summer camp and we want to set up an online registration system where families can decide which classes they want to take, submit their registration info, and pay the registration fee online. Taking a look at the different modules available, it appears that the best option is to use the ecommerce module and add each class as a "product". This is relatively straightforward, but the problem arises during checkout. I need to capture additional information. For example, a family may have three people who wish to attend the summer camp.

mlm (mailing list manager) doesn't seem to send the subscribe message to an external ezmlm server. Has anybody had any success with it? There is absolutey no documentation on it.

I need to develop a web site which will need to have a right block for navigation where there will be a certain number of links.
I need to add a javascript code to each link so that onMouseOver I will get a popup menu that will give me sub-navigation options.
Is that easily achieavable under drupal? Would I have to write a block module for it and the js on a separate file? How would I integrate the two things and how can I go on about it?

I am writing a custom block that dynamically builds a menu. I want to change the subject/heading/title of the block based on which menu i have loaded.
Note this is NOT hook_block() in a module, this is PHP code in a custom block

Hello

i have just installed gallery 2, and the drupal module, and although it seems to be working to an extent I am not hugely sure it is working properly.

the random image does not actually show an image, and when you use the gallery it is very very small! I am not sure whether this is an issue with the theme or not (civicspace). I am using drupal 4.6. Please check it out yourself

Hello

I try to create some one feedback forms. My site needs to have more than one regarding to several services offered and they need to have more fields than in the feedback.module offered.
Because I am using 4.7 b5 I tried feedback first. I found out how to add several more fields to it but I also need some select and multiselect menus. I watched in the flexinode files for the select.inc paste and copied the code for the select menu definition in the feedback and got it to show up. But how do I define the options for this? I tried it in the pipe way like you can do it in the flexinode module eg. Herr|Frau but it didn' show up. I also looked in the database in a newly created flexinode for the options and copied this stuff in the definition like this a:1:{i:1;s:0:"";} to the place where the 3 ??? are. Also didn't work. Any clue what I have to do?

if ( variable_get("feedback_field_anrede", t('Anrede')) )
$form['feedback_field_anrede'] = array (
'#type' => 'select',
'#title' => t('Anrede'),
'#default_value' => $edit['feedback_field_anrede'],
'#options' => ???,
);

It also shall be added to a database where the admin can look over the different email form request I think I can make this by adding the db code to the function feedback_send_email(). Due to the need of more forms can I just duplicate the feedback.module rename it and its included functions?
