You're up to L26 I see, so you have some options. My first club purchase was the WGT Pro tier driver to get an extra 20 yards off the tee. The L30 R11 3-wood is a great club for the price. At L48, I highly recommend the R1 driver. At L35 the Ghost Spider is an excellent value for a putter and a nice upgrade.
At L27-31, I like the Cleveland 56, 60, and 64 wedges. Getting rid of the hybrid and putting 3 wedges in your bag is a great weapon for scoring. I went with the L15 irons, but I hear the L32 R11s are pretty nice. I was too impatient to wait for them. At L59, I highly recommend the Ping G25s...the high trajectory makes a huge difference.
Once you get some clubs upgraded, the L33 Callaway or L11 Srixon are good balls for the price. I know some Tour Legends who still use the L33 Cally. There are also some decent values in some of the WGT balls...they're not great balls but are super cheap.
All of that stuff will hold you over very well until L70+ and is plenty to get to Legend... there are a number of potential club upgrades between L70 and L90, especially if you move up to Legend and need the extra distance. So far I see you've only played one ranked round. If you want to progress through the tiers, you'll need to play a lot of ranked rounds. That's obviously an if and there are posts that will tell you the exact number and average you need to move up. Looking at your history, I'm not sure how you moved from Hack to Amateur :)
In the end, it all comes down to how much you want to spend. From a budget standpoint, the longer you can hold off the better.
This game isn't without its problems like any other, but it's an enjoyable game with a good community. It's especially nice to take up "golf" again when I can't really play anymore in real life.
Cheers
