I believe the question you had was which set do I buy not if. If you have the money and don't want to play crappy starters until L59 that is certainly your decision. I had to money to buy better and I did along the way. Wasted money? Yes, just like my RL CC dues. There is no "best way" but this path will give you good clubs as you march to Legend.
LV32 TM R11 set is good. Sell the hybrid. 3495 -100 = 3395
LV27-31 Cleveland wedges buy the 56, 60 and 64. Yes they are expensive but will take you to the L80ish Clevelands that the very best players in the game use. 2985
L19 Spider putter 400 (keep until you can get either the L70 Odyssey or the L77 Nike)
Keep all this till L59 then trade irons for the G25s (big upgrade)
If you like the long ball (and who doesn't) Trade the driver at either 48 or 55 for the R1TP or M1. The G25 at L58 if on a budget.
For my money the best early game 3W is the L33 Calloway xhot (expensive but will take you to L73 for the next xhot ) a cheaper option is the R15 at L41.
That will take you to Legend. At L90 the R15/Rsi set is awesome (using that driver/iron combo myself at L93)
Hope that helps.
