Well, also make sure you use the terrain to your advantage! On the map SG4, there is a gravel trap, if you lead the team, no matter how large on to the trap, just slap some fire on to the gravel and call it good, it sets the trap without needing the button!
Also, you don't want to use Flint and Steel on tall grass because you have a higher chance of missing it and lighting yourself on fire.
If you are being chased on land and have no chance of getting in to water without dying, try leading the team to a narrow area (1 to 2 blocks wide, many blocks long so you don't trap yourself). When they are chasing you in the narrow area, you can light a fire, which wil almost always catch them both. If you are low on hearts, this slows them down enough that you can get away!
I have never been one to use a fishing rod, but if you are chasing a player that you believe is low, you can use the fishing rod to knock themm off track and make them open to the last few hits. (This probably won't be useful for long due to removal rumours.)
I try to keep 3, no more no less, flint and steel at all times. Although I agree that you can never have too much, arrows are always useful! If you are being chased, the 180 turn and shoot has always been effective for me.
I hope I elaborated on this topic in a positive way, and I am always happy to help!
