Congrats on the saw. I too recently bought an R4511.
You will want to read up on aligning the table top. There is a great thread over at Ridgid on this process. A dial indicator (Harbor Freight Tools) and a little patience will reward you. Getting the blade parallel is pretty straight forward. Getting it parallel at 45 degrees requires some work.
I had a Delta T2 fence on an old craftsman contractor saw that required little effort to retro fit onto the Ridgid.
Measure twice, cut three times, start over. Repeat as necessary.
