[Help] Install twrp in Galaxy s5 sm-g900v 6.0.1

Hey there I just got a new samsung galaxy s5, and I have been searching on the internet since yesterday, and haven't been able to find a thread that gives me information about installing custom recovery or installing a rom based in stock without any bloatware.

My phone is the samsung galaxy s5 sm-g900v (not rooted, i haven't been able to do it, maybe it's not posible yet :( )
android 6.0.1
kernel version 3.4.0

So my questions are:

Can I flash the twrp.tar file with odin?

Is there anyway to install a rom based in the stock of samsung but without bloatware?

And finally, can I root android 6.0.1 in my verizon s5?

Thanks in advance :)
