To start I would look at babyshower101.com to get started. At this site they offer a wide range of products and supplies while also giving many ideas on what to do for activities.
A good baby shower theme is based on what gender it will be. I would involve many items that everyone can do when they get there. Many fun activities are best for that party.
Duck themed baby shower is great for a baby shower. Duck is a gender-neutral theme that works for both boys and girls. http://www.newbornbib.com/top-menu/articles/throw-a-baby-duck-themed-baby-shower/
A simple, yet elegant theme for a baby shower would be to do a two or three color theme. For example, my theme was brown and baby blue. So everything at the baby shower was brown and baby blue. It turned out terrific, was low cost and looked very elegant. This way also you get items to match the nursery if they have specific colors in mind.
A good baby shower idea that is memorable and special is to find out whether the baby is a boy or girl. Then find out if the parents have particular themes for their child and have everyone dress up in that theme. Also take lots of pictures or video to give to the expecting parents.

Following are some fun ideas for a baby shower: Stork delivery theme, nursery rhyme theme, a Velveteen Rabbit theme or The Very Hungry Caterpillar theme. Just be sure to have lots of color and fun foods.
A centerpiece with a picture of a Baby boy on it or a Baby girl is a really good idea for a baby shower centerpieces. Also a picture of a diaper and a binkie might be good.
A good theme would be something both males and females can appreciate- like a backyard party or a bbq. If the theme is too femanine the males will not be interested. But if the sex of the baby is known and revealed to guests- then the theme should pertain to the sex of the baby.
This sounds like a fun theme. You could design a baby rattle or a character such as Elmo or Cookie Monster for the top. You could also use pink flowers for a girl or blue flowers for a boy if you know the sex of the baby.
For a zoo themed baby shower, a good idea would be to get different decorations with different animals. Make (or buy) a cake with animals on it. You can serve snacks such as goldfish, animal crackers and nuts.
If you are planning to have a shower with neutral colors you should go with shades of green, yellow, or brown. All of these colors are suitable for a shower when you don't know if it's a boy or girl.
