Now, what do you mean about the "DAZ installer doesn't give you the option of removing the object yourself".  

All you need to know is where that object got installed.  Really, in some ways, you don't even need to know that.  Just set up your object in DAZ and texture it as you would like.  Then go to Export and export the object as an obj file.  Keep an eye on where you export it.  I keep a file folder especially for my exports from DAZ.

Now, bo into Bryce and import it.  It should come in with all of it's textures.  You can also use the buttons that allow you to switch between Bryce and DAZ, but to be quite honest, I'm not fond of them and don't much use them.  Part of the problem (for me), is that I never can remember which of the two programs I have to start first to get that interlink to work.

One thing I would suggest doing, just as an experiment, is to do a really simple scene with just a sphere or two and see what happens when you click on something with the control key, or the alt key, or both.   There are a number of shortcuts that can be really helpful.

Could be worse, could be raining.
