Venus GPS with SMA connector is a good option for me?

Hi

I am new in GPS wiring, its my first project using georeference devices, so I have questions about the Venus one, because this is the module that I can purchase in the country what I actually, (Brazil) from the sparkfun distributor. I would purchase another GPS module in the case of the Venus isn’t the proper one, but it’s is a long and expensive process from here.

I want to track a bycicle from a GPS using an arduino Duemilanove, I will want to send the logs from the GPS via a X-Bee module. I will have to use a Board for FT232RL USB to Serial in order to power correctly the GPS. Reading the posts, it seems that I will need an aditional antenna, so what would be a good option for me?

The bicycle is going to run outdoors (obviously) in a University campus - free of buildings, so I guess that these are good conditions to run the tracking.

I can do that with the Venus GPS? Which other can be used for? What about the arduino shield?

What kind of antenna do I need?

I would really apreciate some help
