I don't like the flowers as indicators of sharpness, but in looking at your two linked pix, the very foreground of your pics are in better focus than the subject area.
As mentioned, the lens is certainly capable of better results. You could try some varied focus shots. However, I posted in another thread, a method to check the focus of the camera, since the negative area is big enough to use a ground glass. I cut a ground glass so it fits directly on the film plane with the back open (remember to put the frosted side toward the lens). Mount the camera on a tripod and check with a loupe on the ground glass, the relationship of sharp to the rangefinder. I tape the GG to the camera, again so that it fits on the inner two shiny surfaces along the film plane.
As far as using a tripod, I shoot the heavier Fuji's before the fixed lens. It's difficult to answer the "should you...." question because we all handhold at different rates of steadiness, but given the negative size and camera weight (even though your's is lighter than mine) I generally prefer a tripod. The tripod is my best "sharpness" tool in my euipment.
Try the tripod. Then check the rangefinder focus. Again, I thinkyour rangefinder is adjusted a bit toward Front Focus, so try focusing further back,,,, say somewhat behind the subject point of desired focus.
I always send my Big Fujica/Fuji cameras to Frank Marsh at Camera Wiz. He's somewhat of a specialist on these and very reasonable. He's in Harrisburg VA. He may still have an eMail but responds best by telephone. I've used him a lot, but don't think I've ever seen an eMail back from him. He speaks fluent english and is not that hard to get to the phone.
Good luck. Your camera can do better. No doubt in my mind. Also use a subject that has more definitive detail lines. Flowers do not. Also, some people are disappointed that these cameras are not good on Macro. Shortest sharp focus distance is between 3-4 feet. But from 4 feet to infinity, the Fuji EBC coated lens should be tack sharp, properly focused. Also try the distance scale on the lens against a measured distance. That should work well.
