That bike has loads of potential, (carbon frame? -my eyes are dim I cannot see…mmmm!)
I would use the parts that came with it to train on and while you save and get fit for racing if thats your goal and then upgrade bits 2 months before a race.
If people hate the saddle (which he is changing), anyone want to donate one to him???
Or setup a paypal account for the OP and 20 of us donate a quid… 8)
