How to display all taxonomy term fields when adding node in Drupal

Question

I'm trying to make form to post advert in newspaper and want to let user select style of future post and show how it will be printed. So i create taxonomy vocab. "style" with name, sample image and max. characters to this type. Next i'm creating field taxonomy term relation in advert content type.

Now i need to show in adding form not just radios or select with titles but title, sample image and other fields from taxonomy.

I think i need to use hook_form_alter so i use mymodule_form_ad_node_form_alter(&$form, &$form_state, $form_id) but what i can't understand is how in drupal way i can get rest of taxonomy fields? In $form array is only tids and titles.

Is it possible not to query DB again but setup existing query to retrieve all fields i need?
Also how i can insert that additional information into form? Is it other way than #suffix #prefix on radios?

If this is a Drupal 7 then you can use an Entity Reference field along with the Entity Reference view widget instead of a term reference field. That will allow you to specify a view to use to populate the field options, and you can create an entity reference view that display the additional taxonomy term fields you want to display.
