In short, I'm echoing warkings. Train mostly Combat. Train a little Magic as you need it, maybe 55 would be sufficient. Additional training will prepare you for the next tier, but won't provide many benefits over Combat, unless you use bows and arrows.
I'm a mage, primarily, but I still recommend training combat, first, like I did. Magic is trained when you teleport or cast spells to use while training combat, so you don't really need to focus on it until you get an item that needs a higher level, or are preparing to buy one. If you want to prepare, you could train to Magic 55 to wear the best stuff for the middle tier, including Silver Gauntlets.
If you're a ranger, who likes using the weapon boost of bows and arrows, Magic 65 is a big help, once you have the 20k gold to buy a diamond ring. Otherwise, the Combat 55 Steel Shield is almost as good and doesn't cost much. (You can't wield a bow and a shield, but you can wield a bow and a ring.)
Eventually, you'll want 70 combat, 72 magic and beyond, but that's the highest tier. By that time, you'll probably have your own strategy in mind from experience and preferences.
