Also, if you're planning to do the side content anyway then it makes sense to do it now when it can save you some gil. You can very quickly get up to the second tier of Eden, which gives you i480 gear. Some of that, some tome gear and whatever you pick up from MSQ dungeons will get you well on the way to i490 and then if you really need to, you buy crafted gear to replace your weakest items at the end of it.
For that matter, in less than two weeks you'll be able to get augmented Cryptlurker i530 gear with poetics, so you can replace some more pieces then.
Overall I'd say the priority is doing all the story content you can get through once, doing those specific older raids that have been recommended, and not trying to gear up fully until 6.0 changes the level 80 gear to poetics.
