OnlytheStrong, a suggestion: Point Blank Shot and Precise Shot aren't really going to help you much if you intend to be a healer. Since S@squ@tch is allowing the entire Complete series, I suggest the Touch of Healing reserve feat from Complete Champion. Possibly also Healing Devotion as well.
[sblock=Touch of Healing]
Requires: Ability to cast 2nd-level spells.
Benefit: (paraphrased) As long as you have a Conjuration (Healing) spell of 2nd level or higher available to cast, you can touch a target to heal 3 hit points per level of the highest-level Conj(Heal) spell you have available as a standard action. This healing cannot take the target above 1/2 health.
As a secondary benefit, you gain a +1 competence bonus to your caster level when casting Conj(Heal) spells.[/sblock]
[sblock=Healing Devotion]
Benefit: Once per day as an immediate action, gain Fast Healing 1 (+1 per 5 character levels) for 1 minute. This effect activates immediately if you have a daily use left and you fall below 0 health.
Alternately, you can use a full-round action to touch someone and grant them the fast healing. This counts as a daily use.
You can recharge a daily use of this feat by spending a turn undead use.[/sblock]
Basically, two ways to heal everyone after a fight without having to use up limited resources. Note that as a good cleric, you
always have a Conjuration (Healing) spell available to cast as long as you have a spell remaining, because of your spontaneous healing ability.
Note that I'm not trying to pigeonhole you as a healer; it's just that clerics have very very very few ranged touch spells worth casting, and your crossbow isn't really going to do much more than irritate a giant
