you can't charge an hourly rate... the client will expect a million photos. treat this in the same manor as a portrait shoot. charge them a "sitting fee" where the sitting fee is your time to cover the event. do not include any prints in this price. this price should be for home games only and any games that are at different venues should include a surcharge for travel
how are you planning on presenting the images to your client? you have a few options. the best / easiest way would be to create a simple gallery and put them online, either using the web based gallery in photoshop (look into the flash based one in cs2 so they can't right click and save as) or using software, like gallery or coppermine. then make up a simple spreadsheet and have those who want to order prints write the print name / size / quantity on the form and give it back to you, then make the prints.
if they don't have the internet, you can easily put this on CD for them, again using photoshop cs2's flash based web gallery.
another option would be to use photoshop cs or cs2's contact sheet function to print thumbnails on an 8.5x11 sheet(s) of paper w/ the file names under them and pass out one or two of them to the team, again w/ the same spreadsheets for taking orders.
you could also consider doing a package deal... say for X amount of money, they get one 8x12, two 5x7's and 8 wallet prints, a savings of 5-10% over what the individual prices would be.
like others said, do not undervalue your services.
