Where about in Central IL are you? I'm just SW of Bloomington. I bowfish on Evergreen Lake near Hudson, Clinton Lake in Clinton and Dawson at Moraine View State Park. Of course, there's the IL River.
Shelbyville is a really good bowfishing lake.
You're bowfishing package is a good starting point.(kudos to your wife for buying it for you.

) I would definitely get another arrow if I were you.
If you have any questions about any specific lakes, just ask. Somebody around here probably knows about it.
