Looking into trying out some different types of teams. Thinking about building a pitching staff focusing HR/9 and limiting homers. Should I then build a group of hitters that doesn't hit homers and are more doubles/OBP guys or go the opposite way and go a team that hits a lot of homers. 

Basically I'm wondering whether it's beneficial to go WITH the trend your pitchers stop or go AGAINST it? Any ideas? Or has anybody tried something similar? And how can ballparks be used to really help your team?

It depends on your stadium.  I think the consensus opinion is your players weakness should contrast with your stadium choice and your players strengths should compliment your stadium choice.

For example if you played in the AT&T you could draft pitchers with higher HR/9 knowing that the stadium would keep down the HRs anyway.  On the other hand you might look for hitters with high 1B/AB and high 3B/AB.

Keep in mind two things:
In general it is harder to match pitchers to stadiums.  Pitchers only have three types of performance stats of note: HR/9, BB/9 and oavg.
In an OL it is very possible to draft a low oavg, low bb/9 and low HR/9 pitching staff at reasonable cost.

What about WHIP?

What about WHIP? 

WHIP is a stat that combines bb/9 and oav. A pitcher with a good whip is a pitcher who's combined stats for these two are good. This is a good stat to look at if you have reasons to treat walks and hits similarly (mostly in neutral or near-neutral parks).

h/9 = oav * (27 + h/9 - dp/9)
dp/9 ~= 1.4
h/9 = oav * (27 + h/9 - 1.4)
h/9 = oav * (25.6 +/h/9)
1/oav * h/9 = 25.6 + h/9
1/oav * h/9 - h/9 = 25.6
h/9 * (1/oav - 1) = 25.6
h/9 = 25.6 / (1/oav -1)
h/9 = 25.6 * oav / (1 - oav)

whip = (h/9 +bb/9)/ 9
whip = (25.6 * oav / (1 - oav) + bb/9) / 9
whip = [2.84 * oav / (1-oav)]  +  [bb/9 / 9]

There you go.
