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.
