I need to limit FTP traffic to 512Kb so it doesn't max out the internet connection and cause RDP sessions to suffer terrible performance. If anyone can point me to documents to get started with the configuration it would be greatly appreciated. Or, if QOS isn't the answer to my problem, any suggestions are welcome.

What kind of Internet connection? If the bandwidth being maxed out, inbound, outbound or both?

You could use a policy-map to limit FTP. But if RDP is very important you can also use it to prioritize RDP.
You first define access-list with the traffic you want to control, then class-maps to match the traffic in the access-lists and finally bind it to the policy-map. The policy-map is applied on the interface as outbound.
As a sample you could use the below
ip access-list ext ftp-acl
match tcp any any eq 21
match tcp any any eq 20
class-map ftp-class
match ip ftp-acl
policy-map outbound
class ftp-class
bandwitdh 512
class class-default
bandwith xxxx (remaining or full bandwidth)
interface (internet interface)
service-policy out outbound

This will only match for active ftp which is not widely used.
Use:
match protocol ftp
