So, Mickey, have you purchased that bike or bike rack yet? Do share when you do.... plus, depending on where you live, we might have some good suggestions on bike-friendly places you could hit the road or trails.
Do get a decent helmet, btw... and, depending on how much you will ride, you might want a pair of padded bike shorts (to protect those "sensitive areas" -- even if you have a fancy saddle, the padded shorts make all the difference in the world.)
If you find you have any issues with numbness or blisters or plan to go on long rides, a pair of cycling gloves is useful too... they do not have to be fancy, but I prefer ones with gel padding vs. just foam -- they seem to hold up longer and, at least for mountain biking or rough roads, seem to cut down the vibration a bit better. I have notoriously pain-prone wrists due to all my computer use, so I am sensitive to vibration and extended pressure on my wrists.
The only MUST HAVES though are your bike and a helmet -- protect your noggin from fallin!
