Honestly if you install them correctly (and you have Spore installed in the default directories) it should work. Therefore, there was a step you missed or you have something that's not in the correct directory, something you didn't unpack or unzip, or something similar.
The problem with mods is not that they "degrade performance" (that's like saying cars in a parking garage are causing traffic jams on the street) or that they are poorly written --
the problem is that most of the time you are entirely on your own to make sure you back up the correct files, and put the new files in the correct places. It's almost impossible to get help from EA for the programs you lease from them -- you are going to have a hard time getting help without giving better information about what you did and what you thought you did.
First rule of modding your code -- if you think it's not dead simple to do it -- forget about doing it, or wait until someone can be sitting next to you to help you understand.
