Seems like there are two issues here:
Baulking into gear - usually there is a "baulk" ring in the gearbox whose purpose is to resist the selection of a gear until the synco ring has matched the speed of the selected gears to provide a smooth engagement.
Grinding into gear - caused by (assuming the clutch is disengaged) - brute force shifting, trying to shift too quickly before the synco ring has speed matched the engaging gears.

In either case the answer is in the timing..there is a speed for every upshift that would give a perfect shift even if you had no syncro mesh at all, you just have to practice until you find it. Similar with baulking on the downshift, you have to add a little throttle, timed so that the engine speed matches the gearbox "speed" when you engage the gear (may need to double declutch if the box is cold or extra reluctant).
