Module development and code questions

Hello,
I'd like to set 1 font by default (Arial) with 2 different sizes and colours in my TinyMCE Editor.
I'd like to avoid to pass by the configuration with the backoffice. It seems that it's possible by updating the good stylesheet.
But there are many stylesheets in the module. Do you know which is the good one?
Thank you very much.

We have a new challange. A customer likes to sell pipes on their site. Pipes have various diameters, colors and lengths. Diameters and colors are no problem but the lengths are. People need to be able to order various pipe lengths. This should be every possible length from 1 cm up to 6 meters. The cart would look like:
4x pipe 550 cm
3x pipe 375 cm

Any idea how to produce this function? Is it possible to extend the product with a user generated variable?

I am developing a module. With one of its forms, I would like to upload a file. But I always failed. my form is like below:

function my_form($node){
  // Other form elements here

  // And now, the upload widget
  $form['file'] = array('#type' => 'file', '#title' => t('Upload fIle'));
  
  return $form;
}

I check if file uploaded or not if my_form_validate():

function my_form_validate($node){
if ($file = file_check_upload('file')){
// Do somthing here
}
}

Hello all. I'm working with the audio module along with the getid3 and playlist maker. Now so far its good for bringing in one audio at a time but I'm going to have mass audio. I like the way the playlist present itself but I need to find a way to get the audio imported into the site when its alot of audio. Now I already have the audio up on the server and I moved the files first to tmp/audio thenm I went into my site and went to import audio and it showed a very very long list of the audio files. I selected only one of them to import to see what will happen.
