I see people put all 5 points into one thing into their stats once they level. If I did like 2 here and 2 here and one there would that be a bad idea?

Yes..

Why?

Not at all,I am lv92 rogue atm and I do a 2:1:2 with str:dex:vit and it helps a lot and it works well but look at your class forums for a guide or to ask a question regarding leveling and stat points

it all comes down to what type of player you are.

ask yourself...
do you want to be a pure kser/dps? (cons mean low vit high str, uses a fair bit of idols but gets the kill and helps kill faster)
or do you want to be a leveling/alll rounder build?(live for a decent amount of time, dosent needa idol much and can kill efficiently Solo).
or wanna be pure tank? (takes ages to kill stuff but you can solo 4* efficiently if you got the time, and you can tank bosses efficiently, but cant get kills and takes too long to solo level.)

No

Nope

Its ur choice what u want to do and if u dont like the stats u got ur able to just get a book of rebirth and reset all .
