I'm Hosting a Baby Shower! Decorating is driving me crazy! I need help!?

There are four of us hosting and around 60 invited guest! We really don't have a theme, the colors or lavender, soft green and brown! I got lanterns to hang, matching tableclothes, etc... We will have a table at the entrance with the favors and 11x14 Sonogram Picture! The food table...does it need to be decorated with things other than the food or will it look to boring not being decorated with things...like a framed thank you poem, small floral arrangments, confetti? Should I have layered height to the table? I just need to know if I'm going overboard? We have already spent about three hundred dollars and still have to do food and prizes! HELP!
