For starters, you probably want to sell the points in-game. While you can't literally sell the points, you can use the points to buy items which are most often tradable, so the person you're trading with will ask for some items, you buy them with your points, and then you trade those items for his in game money. Once you have a bit of money, you can look around for some equipment.
Thing is though, the PvP/PvM special sets (the ones that are found in the honor shop, purchased with honor which you gain from doing PvP, or valor shop, which you gain from running dungeons) are character locked, so you can't buy these from other players. Look around for a reinforced set, this is crafted and tradable. The most important part is the weapon, which luckily is tradable. It's also generally the item that will cost you the most (a +15 epic will be several billions of in game currency, although it can be less depending on which class the weapon is for and the mood of the seller).
Accessories and back item/mask are also all tradable, so you can get those as well.
Save some of your IM points for refine enhancers (plutorunes to prevent degrading, venurunes to increase refining chance, etc.). Since you'll eventually have to work towards your PvP/PvM sets which are character locked, you'll have to refine these sets yourself. Which is currently not very easy to do with just in game materials, so it's a good idea to keep some IM points leftover for thsoe.
I forgot to say this earlier, but since you have IM points, you can buy an unrefined epic weapon for very cheap, and then use your IM points to buy plutos and venus to try refining it yourself.
