Hi rhodesy, like Manz mentions Zoom Area (on the faint toolbar at the bottom of a viewport) can help with this because it makes it easier to focus in on a specific point. Otherwise it is kind of easy to sort of slide past a point.
With Zoom area, the first point you pick will become the center of the view and also become the "target" point that you pivot and zoom about.
Then after that to do a kind of "fine grained" zoom try using the zoom button on that same toolbar (click and hold down the mouse button on it and slide up or down a little bit with the button still held down). That can do a kind of more subtle zoom than the scroll wheel if you only move your mouse a small distance.
Another option in v2 is to set the 3D view to have a "Parallel" view projection, which should be immune to this clipping problem. To do that go to Options / View / 3D View Projection: and switch it to Paralllel.
The way that 3D graphics cards work requires a near clipping plane to be set up when doing a perspective projection, and one side effect from the way they function is that the resolution of the depth buffer gets pretty bad if the near plane is set to be too tiny, so it is not really an easy thing to fix in a perspective 3D view without causing some problems for drawing the stuff further behind in the scene...
