Welcome to the forum. You picked a great car...I have a '52 too!
Don't hesitate to ask any questions you may have. The answers are here.
A service manual is a must-have, preferably an original because sometimes the repros don't have clear pictures. A parts book can't hurt, either. eBay is your friend. The factory issued service manuals covering a range of years, so the one you should look for is the '46-'52 edition. Other editions (like '46-'51 and '46-'54) are also useful, but may vary on year-specific items.
Like the owners' manual says...'good going in your new Plymouth'
