Hi luckyluke3751 ,
Congratulations for your job , I work as Cisco TAC engineer , I remember the moment when I earned my CCNA certification a year ago. I agree with you "Walk before you can run ", CCNA R&S will help you to understand the basics of networking in almost any aspect , but is up to you if you want to continue the R&S path or go directly to something maybe more related to your currently job as CCNA SP.
On the next step , a CCNP certification of SP will be highly valuable for companies , but is always useful have knowledge in R&S, If you think you can and have the determination , I would bet to earn both.
Regards ,
