No experience with any of those cartridges, or with your tonearm for that matter, but what the cartridges that reportedly perform well on your arm all have in common is fairly high compliance. This makes perfect sense. Your arm is relatively low in effective mass (9.5g according to SME documents turned up by Google searches), which means it was designed for high compliance cartridges.
The Denon 103, OTOH, is a pretty low compliance cartridge. It likes a tonearm of 20g effective mass or higher, and is one of the worst possible matches for 9.5g tonearm.
Changing your bearings would improve the arm in general, but would not normally alter its effective mass. More than that would be needed to get a 103 to play its best. I can't imagine it would be worth the trouble and risk just for that. The 103 is a reasonably good cartridge on the right arm, especially for the money, but there are plenty of good cartridges out there with more suitable characteristics for the arm you actually have. Forget the 103 unless you're prepared to change tonearms. Check out Raul's thread "Who needs MC when we have MM" for many high compliance choices that should perform well on an SME 3009 S2 Improved.
Arm/table matching is fairly insignificant. If the arm fits the table and isn't too heavy for the suspension then you're unlikely to have any issues. I believe your table has no suspension, so for you it's even less significant. Matching of cartridge to arm and cartridge to phono stage are both 1000 times more important. Focus on those.
