Don't rush anything. God knows what's in your heart.
Start with a good Quran translation & read it. In English, Yusuf Ali, Arberry, & Mohammed Asad are all really good. Pick one with a style of language that you feel comfortable with. Read it from beginning to end. Can't get a book? There are lots of iPad & Android apps. This is my favorite: https://play.google.com/store/apps/details?id=com.guidedways.iQuranPro&hl=en & there is a free Lite version as well.
I was born & raised Muslim, I'm in my 30s & I don't speak a word of Arabic. I can read enough to read the Quran & I can say the prayers but that's it. This is probably true of the vast majority of Muslims in the world. Don't let that be the roadblock.
My advice would be don't say anything to your family until you feel more certain. In the meantime sound them out tactfully...bring up Islam in conversation in a more general way & see how they react.
Honestly if/when you are ready nothing will hold you back & you will know. And you won't need us to tell you anything. :)
Edit: This is a great book if you aren't ready for the entire Quran (which is not an easy read) yet. http://www.amazon.com/Approaching-Quran-The-Early-Revelations/dp/1883991692
Try IQuran, Amazing app with recitation from different famous people. And translation from a lot of langueges and a lot for English.
And not a single add.
