October Plugins Worth the Trouble?

I’ve hooked up one of my sites with October, and one of my clients are wondering if there’s a way I can add a blogging service to their site. I see there are plenty of October plugins for this (and a good many other things). I have never used October before, and I was wondering if it would be worth trying to integrate some of the plugins into my blocs website. Will I end up writing a bunch of my own css in the end, or does blocs already have some styles (or, “themes” as october would call it?) for this sort of thing? Any advice from someone who has already done this is appreciated.
