Buttons and Forms - Output Options? Getting rid of blue text?

I'm looking to create an automated InDesign template, over an Illustrator background - ideally this will be used by our admin assistant while I'm gone or a fast way to do it while I'm rushed - to create posters in Acrobat that still preserves our branding and look.

I essentially want to create what would be:

1. some text fields for free input - like the theme of the event
2. location fields for combo or list boxes - like the location
3. date fields
4. time of day fields

5. selectable variables (will snacks be served? will there be a translator?) that will only appear when selected

When I output to Acrobat, what I get are combo boxes that end up printing with a blue background.

1. Is there some way to turn the background off, or turn it to white/no colour? I can always create white "fields" behind the text locations, but the blue will not work.
2. Is there some way to make sure that certain effects or combinations stay 'located' within a certain area of the document? (text aligned to the right/automatically centred paragraph/text automatically sized to fit an output box?)
