Is this a new board? If it's new and you don't tune your edges, just go ride it. I suggest, though, you detune the nose and tail if they are not. This is fairly easy to do with just a bastard file, though it can take quite a bit of work. Use a double cut bastard file or accelerate this. You can also use a dremel tool, angle grinder or bench grinder but you have to be careful with these.
If the board is already tuned the way you want it and it's just dulled, just have the edges brought back to the sharpness you desire with a base edge file guide and side edge file guide. Make sure you have the guide set to whatever the tuned set is. You can do this yourself or have the shop do it. You don't necessarily have to have it sharpened. Some people I know prefer to just let them naturally detune themselves and if you like the way it rides, you don't have to do anything.
At the very least, you should deburr it with a diamond stone and hard gummy stone, even if you aren't going to do a full tune.
If you live in South Jersey, take it to D&Q in Cherry Hill. They have a full shop there.
