As we already discussed, the 3.5 ranger is a different creature altogether. The main thing is that it has been powered up considerably, gaining more skill points, more class abilities, and more potent class features. However, it does have only a d8 HD.
Rather than try to make your ranger into the 3.5 ranger, I'll just say what I think would be some things you may wish to consider.
First of all, Intuit Direction and Wilderness Lore are no longer skills in 3.5. They have been combined into a skill called Survival that deals with a character's ability to live off the land and what not. This is an important change, and I think it should be included if you revise this class.
Second, depending on what your vision of the ranger is, you can take the rest of what I say with a grain of salt. I prefer a more skill-oriented wilderness survivor as opposed to a warrior who knows his way around the woods. IMO, I think the ranger can be developed into its own unique flavor by emphasizing the skills as opposed to combat (which brings it closer to the figher, or better yet, the barbarian) or nature magic (which brings it closer to the druid or nature clerics). For what it's worth, I do not see the ranger as a fighter/druid hybrid or a fighter/nature cleric hybrid. I think it would ideally be closer to the rogue in that it distinguishes itself through skills, but unlike the rogue in that it fills a particular niche and has different abilities. Rather, I prefer the structure of the rogue class, but with class abilities more suited to the ranger.
Now, as for what I think it needs:
Bigger boost in non-combat abilities to emphasize the expertise in living in the wild. Might I suggest bonus non-combat feats such as: Alertness, Athletic (+2 to Climb and Swim checks), Endurance, Great Fortitude, Lightning Reflexes, Run, Self-Sufficient (+2 to Heal and Survival checks), Skill focus, Stealthy (+2 to Hide and Move Silently checks), Toughness, and Track? Also, the Skill Mastery ability from the rogue class seems like it would fit the ranger too.
The 3.5 ranger has an ability called Wild Empathy. It replaces the Animal Empathy skill. The PHB essentially makes it a skill check using your level as the ranks added to your Charisma modifier, but there is room for improvement. Perhaps a synergy bonus for Knowledge (nature)? What about modifying the roll based on Wisdom for determining the attitude of an animal, and Charisma for influencing the attitude?
Natural Healing has great potential. However, I think basing it off Knowledge (nature) and Profession (herbalist) may be a better option than Wilderness Lore/Survival. Maybe use one as the base and the other as a synergy bonus?
I've always wondered why rangers never had a favored terrain, and how things would work if they did have it. A level-based bonus to skills like Hide, Knowledge (nature), Move Silently, and Survival is a good start.
As for combat options, I'd simply allow them to be bonus feats. Virtual feats just make things more complicated. My suggestion would be to limit bonus feats to things that your average hunter or scout would use, not what Rambo has. You could make it easier to get combat abilities, but not overpower or outstrip the fighter in combat abilities for any one style. You could expand the bonus feat list I have above to include a few combat feats such as: Dodge (Mobility, Spring Attack), Exotic Weapon Proficiency, Improved Initiative, Point Blank Shot (Far Shot, Precise Shot), Quick Draw, and Weapon Focus.
I also think some sort of ability related to camouflage could be neat too.
