I have one DC and 2 member servers. I was thinking of adding another server that'll be a second DC to share the load with the other DC. I was wondering if I did do that, is there anything other than doing DCPROMO on the 2nd server that'll need doing? Things like FSMO roles. Should I be concerned about that?

Entirely up to you!
I wouldn't bother too much if its only 2 DCs as you can share enough load (DNS/Authentication/etc) without messing with FSMO roles.

Yep leave the FMSO roles, just make the second DC a DNS server and Global Catalogue and your good to go

I wouldn't bother with making it a global catalogue, unless you have domain trusts in place and many, many users who are crossing the security boundaries. If not, all it will do is generate replication traffic.

Although it will increase the redundancy of the other DC. IF ones fails while your offside they can still run on the other DC.

Only if you have multiple domains. With only one domain in a forest, a global catalogue brings you no additional benefits because its purpose is to allow searching of other domains in the forest without knowing their full name.
Edit: That's unless you're using Exchange in the same domain, which relies on GCs for the global address books.
Edit: Actually, I'm talking total , you need a GC for logon requests Sorry. I haven't had much coffee today.

You got me lost then, i was going to say you need it to logon. We all have those days.
Personally i would have another just in case, it will make more network traffic but on a LAN it wont be noticeable.

This should explain all you need to know about global catalouge servers.
What Is the Global Catalog?: Active Directory
