What the difference between Gaelic and Gaelige? And how different is Scottish Gaelic from Irish Gaelic?
I think you mean Gaeilge - it's just the Irish word for the language.
The Scottish equivalent is Gàidhlig.
You will rarely hear the language referred to as "Gaelic" in the Republic - they usually call it Irish.
It is a very difficult language to learn, as it is not at all phonetic.
You would have problems trying to learn from the written word alone, you need to hear it spoken, as some of the sounds are aspirated (breathed) and formed on the back of the tongue rather than spoken.
I would strongly recommend that if you want to learn Irish, don't even look at Scottish Gaelic......it will confuse the heck out of you!
You can see what I mean here:

The most widely spoken dialects are Munster and Connacht, understood throughout the Republic.
I remember a member of this forum some time ago started learning from an online BBC course, which was Ulster Gaelic. You would probably not be understood in the Republic.
The problem is not only are the words and phrases different but the accent is very harsh. It is closer to Scottish Gaelic. There's an example of it here, a Political broadcast by Gerry Adams (with whom I am NOT on the same page politically by the way!) :

I have recommended several on this Forum in the past.
I'm told Rosetta Stone does a good one, but it's about $600!
There are several Irish TV and Radio stations which broadcast in Irish:
