Are you sure they aren't already downstream of another GFCI device? Personally, I would pick up an inexpensive outlet tester like this one to verify there isn't protection. Pushing the test button simulates a ground fault which would trip a GFCI device. I also would not worry about adding an AFCI receptacle. AFCI breakers protect the whole circuit and can be installed during a later panel upgrade.
If you've verified there isn't a GFCI upstream, you can use the outlet tester to check which outlet is first on the line by disconnecting one (turn off breaker, cap off the wires, turn breaker back on) and seeing if the other is still live. The GFCI receptacle will replace the first outlet, the feed wires will land on the terminal screws marked "line" (usually the top), and the wires feeding downstream devices will be landed on the terminal screws marked "load" (usually the bottom screws).
