You can use an OEM filter or a Amsoil, Wix, or Purofilter (I think that's the name).
I will tell you this though. You will get flack for running Rotella T 5W-40. It's not a motorcycle specific oil, so people are scared to run it. I run it on my '06 636 and I have no problems. I'm also not a track guy, so I'm not going to be riding the bike super hard. Ride on streets and the occasional backroad. At most, I will put 6k miles on my bike in a year. I'm also going to always change my oil between 2-2.5k miles. That's no matter what oil I use. If I use Amsoil, Motul, Rotella, Mobil 1, or whatever else it's going to get changed.
My OWN PERSONAL OPINION is if you don't track a lot or ride the bike in high rpms a lot, you could easily get away running the cheaper Rotella T 5w40 or Rotella 15w40. I'm running 5W40 for the winter months and 15w40 for the spring and summer. I ride year around if it's not raining, so I will need to run two different oils.
If you track and run the bike in higher rpms, I would recommend running Amsoil or Motul, just for the peace of mind. You seem like a person who is just going to be cruising on the streets and using the bike as a commuter, like myself, so the Rotella's should work just as good for us.
The only reason why I'm running Rotella is because I change my oil regardless at 2-2.5k miles and I don't run my bike hard through the rpms. When I rode my Suzuki Bandit I used cheap, motorcycle specific, Valvoline 10w40 oil and I changed it every 1.5-2k miles.
In the end, it's all personal preference. I'm trying to save a buck and getting a gallon of Rotella T 5w40 for $20 at Wally World is good for me. It currently takes me 4-6 months to ride 2k miles for the most part.
