The I-Vibe Rabbit is a good one to get if you're going with a rabbit but that wouln't be my suggestion for a first time toy. It has a rotating cock part and a buzzing rabbit ear clit stimulation part, different settings so that the seperate parts can be turned on or off and run at different speeds and the better models have different settings for various pulsing timings. You can produce some really good orgasms with this thing!
The hitatchi is really good for clitoral stimulation and she can use it while you're fucking her too. It has 2 settings, high and low, low should be fine to start with. And like Stromba said, guys can use this too.
A g-spot vibe is good, it's not thick and it's easy to use on her clit and to tease her by using it on her labia intermittently with her clit. Also a good choice for anal.
A bullet vibe is good because it can be used on her clit/labia but it can also be put in her pussy and you'll feel it too when you're fucking. It can also go in her ass as it's really small and again, you'll feel it during penetration.
