Looks like you are covered on the egg turning situation…so I will address the skew catches.

First of all….every wood turning tool has a chance of catching…a majority of these are caused by incorrect attack angle of the tool towards the wood. The rule of thumb is to place your tool rest so that the tool will be centered (Draw an imaginary verticle line (from headstock to tailstock) down your project along it’s center…the tool should strike this line when laid squarely on the tool rest)

The basic approach is to start with your tool on the rest and with the cutting edge just above center (angled just slightly)....bring the tool down to center as you start your pass. Bring the tool to center as you begin sliding the tool along your cut. Try to make your passes down hill along the grain path. Make sure the cutting edge is not measureably below center or above center – too far below center reduces the tools ability to cut the wood fibres – in a sense it makes the tool a scraper…and it will not remove much material – to far above center makes the tool unstable and subject to catching in surface imperfections… As a beginner, watch the tool untill it begins to cut….it should be slicing off shavings not dust (you can tell the relative sharpness of a tool by compairing the shavings)...as you become more attuned you can then watch the profile of your project as you turn – the ghost image you see as the project turns is the out of round/out of shape…..I watch the profile while I turn…when the ghost is gone, the turning is smooth….

A dull tool will catch much more than a sharp tool….the dull tool will also be much more subject to becoming unstable as it bounces along the surface instead of cutting the fibres.

There are many great DVDs and books out there that discuss the basics of stance and tool use….but the best method is to find a good mentor….someone who can show you how to do it….and then help make sure you get the hang of it…....check for a good local turning club…or for classes at your local woodshop or adult education at a local college. These skills can be self taught….but it is always better to get past the mistakes without having to make them all.

Hmmm….I didn’t see this was such an old post until after I posted.
