Sadly the materia you produce from spiritbonding is completely random. HQ gear only increases the rate at which gear bonds, not the rank or type materia you get. Spiritbonding, especially if you can craft your own gear is generally the cheapest way to get your own materia if you need it. Either way, for the top of the line melds, you are looking at either a lot of time, a lot of money, or both.
As for the best melds for bard, as it is with any damage class, Crit and Det are your number one gunners. Skill speed is really not all that great, especially for a TP guzzler like Bard. Accuracy is neither here nor there. It makes good filler and depending on the kind of gear you have currently, is very helpful when meeting accuracy checks in Coils. However, it is important to note that how you meld your bow is really up to you. Crit, det, skill speed, accuracy... They all serve a purpose, and so long as you aren't throwing shit like piety on there, you will have a decent bow.
Of course, if you want to get that step over with and move onto lights as soon as possible, there is no shame in making a Welfare Relic, and replacing the materia as you are able to buy them at a later date. You can switch materia at any step in your relic quest line, even with a Zeta! It is very easy and not costly to do if you do so at your own pace. All it requires is materia, alexandrite, and another sphere scroll, so do not so worry about having the best materia all at once.
