It's a good thing you didn't wait longer. I wish you had purchased the topper at the time you bought the mattress.
The latex topper provides long lasting surface comfort, retards the wear of the mattress...and, sleeps cool.
So, yes. Adding one now will geartly improve your comfort and keep the mattress from the premature wear, that normally would occur.
I suggest the EverEden 2" Soft Vytex Dunlop Latex topper for you. The Dunlop is just a bit more dense than the Talalay, which will wear better under a man your size.
Here is a link to those latex toppers:
