Yep. Provide a place for them to shoot and see if you can find local pro that maybe you could hook new shooters up with to get some lessons to get them started out ont he right foot. I agree with Jim, that it is important to carry target archery equipment. How much of it you do carry will depend on the hunter/target archer ratio.
The things I seem to buy most often:
1.) Target Arrows / Fletching
2.) Scope / Sight Accessories
3.) String Accessories
The things that I see most people buying at the local shop during this time of year are
Releases, lenses, scopes, sights, rests, arrows & strings
Here's my opinion on some other things too:
For the rests that you choose to keep in stock, have a variety. The same goes for releases. My personal opinion is that aside from the fit and feel of a bow, the release is the second most intimate piece of the archers setup. It needs to fit the hand perfectly. Everyones hand is different, so they need to have something to choose from.
Like Jim said, sell The Archery Program and have a copy of it for yourself, so that you can ensure that you're selling the right arrow, cut to the right length with the right accessories on it, to the customer.
Hope all this helps. Good luck in your venture.
