A search for "Robert" at the Nexus brings up http://tesnexus.com/downloads/search.php?name=robert&scid=20&author=&mname=&desc=&size1=&size2=&downloads1=&downloads2=&udate1_day=&udate1_month=&udate1_year=&udate2_day=&udate2_month=&udate2_year=&ldate1_day=&ldate1_month=&ldate1_year=&ldate2_day=&ldate2_month=&ldate2_year=&endorsemants=&images=&readme=&advltonly=&opensource=&page=1&orderby=name&order=ASC. Of course, there are a lot of Robart's
Female mods in that list, but even so, there are many that will be for both male and female, or just for male. You'd have to install Robert's Male body to use any of the applicable ones in that list, naturally. But then, that's a better male body than "vanilla", anyway.
As for hairs, you could try doing a search for "hair", and sorting how you like. Or try something like Cobl Races (with the Cosmetics pack) or the Race Balancing Project (very similar, but with more stuff) - these have many hair and eye types included, for guys and girls.
edit: And googling "male armor mods oblivion" brought up http://www.thenexusforums.com/index.php?/topic/87431-male-clothing-and-armor-links/, first of all. No doubt a bunch of other links that might help too...
Oh, and I forgot - you can also browse categories at the Nexus using tags now, some of which are things like "Armor - Males" or "Clothing - Male", for instance.
