Hi Iggy!
I'll leave the e-kit recommendations to others. However, purchasing a practice pad is a great idea regardless. I support
@Hellwyck 's suggestion here. The best reason to get one is that
you can bring it places you can't always bring your e-kit! This means you can practice nearly anywhere at anytime, and it's a drummer's best friend, beginner or pro. Up to you, but if I were you I'd buy one with your e-kit. Also, I can guarantee that using one will improve your technique on the e-drums by like 1000000000%.
The Evans REAL FEEL is pretty universally liked and considered by many the best pad out there. The Millenium True Stroke is a great bargain option, though. I have it, and its performance is similar to the Evans and its a little quieter. (And, it's only 20 euros, unlike the Evans which starts around 40)
Other than that, you can practice your basic rudiments, paradiddles, and other techniques for free on the Drumeo youtube channel. Also check out Rob "Beatdown" Brown, and Emanuelle Caplette on youtube. They will help you progress and prevent a lot of beginner mistakes!
