Hi Aysha,
Do you mean text crossing over from the left page to the right? How is the catalog being bound? Saddle stitched or perfect bound? That’s usually determined by how many pages it is. Fewer number of pages is usually saddle stitched (staples). Larger number of pages becomes too much for saddle stitching and the usual alternative is perfect binding (flat edge spine). If it’s saddle stitched, it’s not that much of a worry to cross from the left page to the right. Set up your file as facing pages. Then you can make a text box cross from one page to the other. I would only do this with large headlines. If the catalog will be perfect bound, it’s much more complicated.
Bleed used when any item will go all the way to edge of the page. You have to have enough image or object to be bigger than the trimmed page size to allow for slight imperfections in cutting and binding. The usual amount is one-eigth inch. The guides in InDesign show you that amount so that you can make sure you drag your items at least that far into the pasteboard.
Slug is not necessary. That’s an additional area in the pasteboard where you can print technical details about the file. It’s mostly used the world of magazine ads.
It sounds like you should do some video self training for beginning users. There are so many things you need to know to create a file that will print without a lot of trouble and expensive fixes at your print vendor. There are lots of them out there. I’d start with Lynda.com or the training at Adobe.
Good luck!
