. . .
my question that regards TM is : would it have helped ?
could i have just chosen the os x's backup of the day before the wrong update installation & got away with it ?
Yes, although you probably wouldn't have had to reinstall your entire system; just restore the previous version of the file(s) in question.
is it that easy to get back in time & correct the mistakes avoiding all the useless roundabout acts like reinstalling risky deletes of files etc. ?
i don't think TM is useless but i am saving for a TC.
Unless you need a wireless router and a way to back up a laptop, a TC may not be worth it to back up an iMac.
as it seems i might just buy an external HD with more GB & get it over with.
Yes, Time Machine will back up to an external HD much faster and more reliably than over a network.
You might want to review the [Time Machine Tutorial|http://www.apple.com/findouthow/mac/#timemachinebasics] and perhaps browse [Time Machine - Frequently Asked Questions|http://web.me.com/pondini/Time_Machine/FAQ.html] (or use the link in *User Tips* at the top of this forum).
