I have a single class wisdom based ranger, she is at level 23 at the moment.
The feats I have taken are as follows:
1: Blindfight
3: Zen Archery
6: Natural Bond (Technically speaking, you now have all the pre-epic feats you need as Wisdom based ranger.)
9: Combat Focus
12: Combat Vigor
15: Combat Awareness
18: Combat Strike (+4 AB and Damage every five minutes)
21: Bane of Enemies (+2d6 Damage against your favored enemies)
23: Epic Animal Companion, Protective Ward (Protective ward could be taken at pre-epic level, it is +2 AC, which I do not need but took because of otherwise I would end up at odd wisdom score.)
25: Great Wisdom I
26: Great Wisdom II
27: Great Wisdom III
29: Great Wisdom IV, Great Wisdom V
The basic way of leveling has been: Buff up my animal companion, you should choose anything other than the badger, and let it tank while I spam Manyshot, or the arrow related reserve feats/spells. As a wisdom based Ranger you do have the benefit of being able to buff your animal companion, yourself, and have enough slots to make use of the ranged reserver arrow spell feat thingies.
Now, this is the way I have gone and you do not have to follow my steps. But once again, as a ranger, do not pick up the badger because your ranger spells are not suited for buffing it up. Anyhow, look here for the stats of some of the Epic Animal Companions:

As for other feats you could consider Pre-epic:
- Steadfast Determination just so you do not fail some saves by rolling a one even while you beat the DC.
- Protective Ward, +1 AC and +2 at level 24.
- Luck of Heroes, +1 to all saves and AC.
- Iron Will for Indomitable Soul? Or just Great Fortitude and Lightning Reflexes for +2 to their respective saves? As a wisdom based ranger your saves tend to be pretty close to one and theother. High Fortitude and Reflex saves with a ton of wisdom to boost your will save.
- Weapon Focus (Shortbow, Longbow, or Sling) Sling can be used with a heavy shield, if you worry about your own AC, and rangers do get Shield proficiency by default.
- Practised Spellcaster (If you do go for something else, like monk dip)
- Last but not least, Able Learner, to spend crossclass skill points at whatever since a ranger gets a ton of them. (6 + intelligence modifier, which means that Ranger is one the rare classes that can get by with starting intelligence of 6!

)
As for feats to consider Epic:
- Epic Prowess? It is +1 AB.

I do not have it, and most of the buffs I use already have long durations. Thus I would actually consider it a wasted feat.

A dexterity based ranger usually reaches 30 dexterity, or slightly more, 32, 34. This is +10, +11, or +12 on your AC if you do not wear any armor.
Now, a wisdom based ranger could leave their dexterity at 14, cast cat's grace to bump it up to 18 and make full use of a regular Chainshirt for +8 AC. Or a mithral Chainmail for +10. Now, if they are a slinger, they can wield that +3 Heavy Shield for a +5 AC.
What I am saying is that you are not that far behind, and anyhow, you will have your buffed up animal companion to tank for you.
