The R11 is a great driver. I had it until I unlocked the L62 R9, so it'll serve you for a long time.
You've still got the start irons, so I'd address that. I really liked what I saw when I tested the L35 G|10 irons, and they're an absolute steal at just 1100 credits. They're even better in some ways than the R11s
L35 Ghost is a great putter. Dumping the starter putter will help you game hugely. Going ghost putts you on a good upgrade schedule, too.
When you unlock the L38/39 Satin wedges or L41/42 Tour Ws, get yourself a 56 or 54, 60, and 64 degree wedge. Dump the hybrid and carry those 3 wedges. Difference between Satin and Tour W is pretty insignificant. Pick whichever you like better.

A setup like that will last you a while, and you shouldn't have to even think about upgrading it until you get to about L60. Then it's time for the R9, and the i15s, but that's way down the road.
