If she was a woman of faith than she would want that faith to be proclaimed to those who came thinking that she was "gone". She would want a final testament to her life to be aimed at the same faith she aimed at. And many of the verses posted to you are great. Or perhaps from Psalm 116 "Precious in the sight of the LORD is the death of his saints." Or Hebrews "For he looked for a city which hath foundations, whose builder and maker is God."
Of course, a critical question is also "what do you believe?". She would want you to also share that saving faith if you were going to be the one to proclaim it. Do you believe what she believed?
If she wasn't a believer than scripture verses can only seek to make you look more "holy" and could be inappropriate. While possibly "true", there is nothing worse than going to an unbelievers funeral and saying "she's in He11 and if YOU don't want to go there this is what you'll do".
If you simply don't know but really want to use Scripture, perhaps verses that speak to who she was? Like Proverbs was used for the Queen Mother "Strength and dignity are her clothing and she laughs at the time to come."
My suggestion? (after an already lengthly answer):
You've lost your grandmother, and if you were close enough that you've been asked to give a eulogy, that can't be an easy thing. Perhaps you should spend a few hours reading through Scripture for your own healing. You might be shocked at what is revealed to you. You just might find exactly what you were looking for.
And of course, you'll be able to truthfully say "I was reading through Scripture to comfort myself at grandma's passing and I came upon the most wonderful thing..."

This is a good suggestion, IMHO.
