I just got an eleuke too. I'm playing with a standard 12 bar blues progression in G, trying to work out Gary Moore's Walkin By Myself. You can get the chords on Chordie dot com and transpose it to whatever key you find playable
I've also been playing Stairway to Heaven from the electric boogaloo site (google it)
Let us know what you work on. I'm just going to drop a note in the forum about 12 bar blues on a standard tuned uke.
