I would suggest getting it on an area like your wrist or the back of your neck, some where that you can hide it if you need to.
The basics are some plain unscented not died soap to wash it with, some thing that doesn't have antibiotics in it, vitamins or any fancy oils.
You should apply either unscented not died lotion, tattoo ointment or some thing like aquaphore to your tattoo when it starts feeling dry or itchy. Nothing but these things should be applied to your new tattoo. If you have to go out in the sun for long periods of time keep your tattoo covered or stay in the shade.
No swimming (or submerging your tattoo under water for long periods of time), no suntanning until your tattoo has completely healed. Don't re wrap it, tattoos need air to heal.
Don't wear tight fitting clothing, straps, or any thing that could rub too much over your tattoo. If you get it on your wrist don't wear watches or bracelets until it's healed.
