Duration is enough time to regrow the lost body part (1 month for digits, 5 months for extremities, 9 months for limbs or eyes). You could presumably reduce Duration markedly by adding in Altered Traits, Regeneration (Slow), which at worst is going to take a month to get you back up to full HP (and thus restore all lost bits, as per the description of Regrowth). Depending on how you interpret that last part, it might even be possible to set Duration as an hour or so, and then simply hit the target with Lesser Restore Body + Healing until they're up to full HP.

My thought was a greater restore to give the advantage and a lesser healing effect to heal the damage. No duration needed.

Unless you've got some ability to cast two spells at once, or you have an assistant (with whom you can coordinate perfectly), you'll have to put at least some duration on the Grant Regrowth effect, or else it will have ended by the time you cast the healing spell. It will probably work out better to put Regeneration (Slow) on that effect, however, so that you can avoid paying the x3 Greater Effect tax on it. Actually, come to think of it, your best bet would probably be to heal all damage first through Lesser Restore Body effects, then give them Regeneration (Slow) with Duration, and finish up by giving them Regrowth. Regrowth + Regeneration means you restore all limbs once you reach full HP, so if you're already at full HP when you gain those traits you would presumably regrow limbs instantly. Even without any Duration, you're still looking at 141 energy for Regrowth, however.

You just build a spell that does two things at once. The few points of healing is likely cheaper than much of a duration.

The "regrow all bits at full HP" clause for Regrowth only applies if you have Regeneration as well*, so you'll need to have that in - and as Regeneration (Slow) should be doable as a Lesser Restore Body, you'll want to have it as its own spell (it costs 17+Duration on its own, but adds at least 30 energy to the cost of the Regrowth ritual if tossed on there). Healing could be tossed on to Regeneration or cast as its own spell, but you probably want to avoid tacking it onto the Regrowth ritual, as otherwise you're paying 3x as much for your healing.
Incidentally, I happen to be working on a racial template that includes Regrowth. After seeing how ridiculous the price was, a quick search revealed that PK did a quick analysis of Regrowth over at his mygurps.com page and determined a maximum fair price for the trait being in the neighborhood of [10]. That drops our Regrowth ritual cost (without duration) from 141 to 51, which is far easier to pull off.

*You could certainly make a case that it should apply even without Regeneration, but keep in mind that RAW Regrowth requires an average of 9 months to regrow an arm, leg, or eye - an HP 10, HT 10 character will have regained 135 HP in that time period just through natural healing.
