I would disagree that the waitstaff doesn't need to be tipped. I think the amount depends on the arrangements the caterer has the waitstaff - but in most cases there should be something budgeted (if service was poor it could be reduced - but you should at least have planned for it). 

If the waitstaff are being paid an hourly wage (higher than a waiter would make) than I would still tip - but less than the 15%.  If I knew the staff was being paid like a waiter I'd do 15%.  I have a separate labor charge with my caterer (so I know they're getting an hourly wage) and I was going to do 8-10% on food and beverages.  I hope that's fair - they say tips are not required but appreciated.  Which usually means they expect something.

I think I would tip the wedding contact at the reception hall if she was present the day of and helped out that day (logistics etc.)

I wasn't planning on tipping my DJ and photographer who both work for themself. I'd reserve gift cards and presents for people you've either worked with extensively through the planning process or "friends" that are providing services.  Like an officiant that is also a friend - a gift would be more appropriate than money.

Tipping is a topic discussed often on these boards:

 Try that link and see if it helps.  I agree with Gaudoir, the wait staff should always be tipped if gratuity is not included in the contract.

 For vendors who own their own company, sometimes the best tips are just a thank you card and an honest review and being available for future references.
