Using a background worker to load form data

Hi.

I have a form that gets populated on the Form_Load event.  It fills a few combo-boxes and tabs as well as it displays all details about a customer.  The time taken to load this information is too long, so what I wanted to do, was to load the first tab, with the most important information, (for eg. name, surname, contact numbers), and then implement a background worker to run after the first tab is loaded.  

This is an example of the function that I want to include in the Background worker :

dsRecords = poCampaignSalesBL.ReturnLanguage()
poDSL.FillComboBoxDataSet(cboLangauge, dsRecords)

This just populates one of the comboboxes.  I want to know if a background worker will work in this situation, and if so, what do I need to do to implement this.
