Rystil,
Is mithral available? Also, are there any bows I'm not aware of? You mentioned powerful, highly expensive, magical ranged weapons.
What is the cost, abilities and feats I need to take to be able to use it one day?

Okey dokey: There is no mithral available, although there are a large number of other materials, some of which reproduce certain of the effects of mithral.
Praetorian Warbows are exotic weapons that are rare outside of Praetorianus; they are quite large and deal 1d10 damage.
Alvasis are exotic magical weapons that store arcane energy and convert it into energetic shots. They can be fired as a weapon, as a ranged attack (not a ranged touch attack though) that counts as magic for the purposes of beating DR, although nonproficient users gain an additional -4 on top of the usual -4 for exotic weapons because it is entirely different than most weapons.
[tangent] Oh, DR, that reminds me that I need to put my houserule about DR up on the front page. I mix and blend the 3.0 and 3.5 DR systems, so some monsters still need +X weapons to penetrate part of their DR (I also have partial penetration for having some of the qualities required of a weapon, but not all).[/tangent]
Back to the Alvasi, creatures do get SR against Alvasi shots, however. Alvasis are nearly impossible to fire correctly, and accuracy is paramount in dealing damage with them, as they can do hideous amounts if they actually hit directly, whereas Strength is completely unimportant, as there is no string that needs to be drawn or such.
There are two sorts of Alvasi, the Light Alvasi and the Heavy Alvasi. Light Alvasis deal 2d6 damage base with a x4 critical. Heavy Alvasis deal 3d6 damage base with a x4 critical. There is a bit of a kickback from firing Alvasis, so it requires a Move-Equivalent Action to resteady aim of a Light Alvasi or a Full-Round Action to resteady the aim of a Heavy Alvasi, neither of which provokes an Attack of Opportunity. The Steady Aim [Alvasi] feat lets you reduce the Light Alvasi resteady to no action (so you can make a full attack, or even dual-wield Light Alvasis, although they aren't light weapons, so the penalty is quite steep) and the Heavy Alvasi resteady as a Move-Equivalent.
Normally, no damage bonus is added to the Alvasi from Strength, though it may be further enhanced with additional magic or elemental energy. However, anyone with Weapon Specialisation in Alvasi can take the Lethal Accuracy [Alvasi] feat, which adds Dexterity bonus to damage with the Light Alvasi and 1.5x Dexterity bonus to damage with the Heavy Alvasi.
The big problem is that Alvasis are a new sort of item that combines magic from different sources, and so they have never been very reliable. On a roll of 1, the Alvasi misfires, releasing a critical hit (which does not add the Marksman's Dex bonus to damage, thankfully!) in an eldritch blast on the Alvasi's user as well as anyone with 5 feet (effectively a very small fireball that deals 8d6 damage, or more if the weapon is enhanced). Everyone except the one who misfired the weapon can make a Reflex save DC 15 + total effective enhancement bonus of the Alvasi, for half damage, but the wielder is automatically affected, and immunity to critical hits does not avoid any of this damage.
The Explosive Precautions [Alvasi] feat (which requires Weapon Focus [Alvasi]) allows the Marksman to make a Reflex save, DC 20 + total effective enhancement bonus of the Alvasi, to negate the effect of a misfire completely, although the Marksman still can't save against the damage if this fails
The Superior Explosive Precautions [Alvasi] feat allows the Marksman to reduce the explosive damage from critical hit damage to normal damage, even on a failed Reflex save.
Alvasis do not use arrows. Instead, when they run out of energy, they can be recharged by casting spells at the Alvasi (so your Arcanist/Marksman will be one of the few who can recharge his own Alvasi). Alvasis can hold 50 spell levels of energy, and Light Alvasis use up 2 of these per shot, while Heavy Alvasis use up 3 per shot. Misfires use quadruple the normal number of levels unless the wielder has the Superior Explosive Precautions feat or there aren't enough levels left for this (in which case, it deals 1d6 damage per level remaining).
Alvasi Masters (Those who take Alvasi Mastery feat, which requires Greater Weapon Focus [Alvasi]) can use a standard-action to absorb incoming ranged attack spells with their Alvasi (although each attempt uses up an Attack of Opportunity), making an opposed attack roll against the spell's caster. If the Alvasi Master wins the opposed attempt, she is able to quickly absorb the spell meant for her into the Alvasi, recharging it and negating the spell.
I think that's it
