Kiku,
The CCNA R&S would be a great first start. It's quite a difficult test, and there's a lot you need to know for it. You can take it in two parts, ICND1 & ICND2. If both parts together are too much information to study for at once, take the tests separately. Once you pass both tests, that's your CCNA right there.
After that, it just depends on your personal interests. If you're interested in Voice technology, or a provider that deals mostly with voice, you should do that. If you're looking to focus on security, you could do that as well. Note that if you're looking just to take the CCNA Voice or CCNA Security, you only need the ICND1 (CCENT) and not the ICND2.
These technologies are so broad that they cover quite a bit of ground. Just the fact that you have your CCNA will help set you apart from the crowd.
Heck, if you find yourself really enjoying the CCNA R&S, you could even go for the CCNP as well.
Hope that helps!
