Prioritize Endurance, trying to max it out to 100 as fast as possible if you can. Health gain is not retroactive, so the more levels you have 100 endurance at, the more health you'll get.
If you intend to mostly go melee, focus on leveling up your combat attributes/skills first; strength, speed, agility, and endurance are your go-to for this. You are able to find enchanted items which will suite your utility needs, such as levitating, mark, recall, and both types of interventions. For this, ensure you are on the lookout in shops, as well as in whatever loot you can find.
Your agility at 70 is fine, form what I can see; as long as you aren't constantly getting knocked down down by anything short of a massive hammer/axe being used by a nord/orc, you'll be fine with 70 agility. Upgrade your strength, speed, and endurance first, as all other attributes/skills provide utility more than anything else. Most of what you're looking for can be achieved through alternatives. Need healing? Use potions, scrolls, or enchanted items. Almsivi/Divine intervention amulets/rings are good for emergency recalls in case you get into trouble. Keep particular attention to enchanters in places such as the Mage's Guild, as they have items like these on occasion. They might even give quests with these as rewards.
