Need help on Razer Blade Stealth 2017 i7 8550U Upgrade Options

Hello folks.

I am a newbie to this.

I would like your advice on some upgrade options for my Razer Blade Stealth 2017 that I currently use with a Razer Core V2 with a Geforce 1070 6GB card. I would like to upgrade the card to a 2080. Is this a good upgrade and will the cpu bottleneck the 2080 card?

I would also like to know if I can upgrade my SSD from a 512gb to a 2tb SSD. If yes, are there any recommended NVMe SSD's that are compatible with this Razer Blade Stealth 2017. Will Gen 4 SSD's work?

I believe the CPU cannot be upgraded here but can the RAM be upgraded from 16GB to 32GB?

Thanks in advance for your suggestions and advice.
