@BlueBard A few little things on outset: having 120 skill in each bard skill allows for a bonus when using these skills; you're aiming for that already and that is great. Other bard bonuses include: a) a bonus for the bard skill whose mastery is active, and b) a bonus for the use of an exceptional instrument.
Regarding what to add to your template, I played a bard w/ Spellweaving on Atlantic years ago and enjoyed it. With SW, you will need 120 Meditation as well as the 120 SW (the mana draw is huge). SW has the advantage of Word of Death, a spell which may be utilized once a mob is down to 30% health and which does
a lot of SDI based damage. You will need excellent mana regen and 120 Med (as well as maxed out SDI) to make this one happen, but it is a nice ability. SW also has a pretty decent Nature's Fury spell: w/ a level 6 Arcane Focus, 4 to 5 of these does more damage than two EV's (plus, NF have pack instinct). Oh, and SW has some neat and handy AoE spells. There are some downsides to SW: the healing is limited (the spell does burst healing and waits on a timer before one may recast), you'll have to time your hunting to coincide w/ getting a full (level 6) Arcane Focus (a group is necessary to make this) and you will have 0 defensive capabilities. Those negatives are really not so bad, but they are there and what they are.
The Magery route, which you are already taking, isn't one I entertained much. I got around without it and just didn't see the appeal or usefulness. Some good things about Magery, though, include: you will be able to dependably travel via spells, heal and even have defensive ability via a -0 (preferably) mage weapon. Also, I have a feeling that Magery is less mana intensive than SW; that said, you will likely still want 120 Med (except for certain situations; more on that below). Also, it is good to keep in mind that you will not likely be able to fit Evaluate Intelligence in any meaningful way which means that damage for many (not all) Magery spells will be underwhelming.
I have heard good things about Mysticism (a lot of people use this on all kinds of templates) but I myself have never used it. I can tell you it relies on Focus and Imbuing to power some of its spells (much like EI powers Magery), so I am not sure how useful this skill will be without properly backing it up. I'm sure others can speak more to this.
Now, mixing two or more of these spell skills on a bard template really crowds it out and dilutes things. Sure, one may drop a bard skill... but now, the bard skills, being absent a bonus, are less effective. Also, being that you'll likely be running bard masteries in one form or another most of the time, the mastery buffs will require 120 Med & 30 Mana Regeneration to be able to run constantly and also be able to do other things w/ your mana pool; these same bard mastery buffs give their greatest benefit when all bard skills are at 120, something you will no longer have once you start dropping skills. This is one of the key reasons I went with SW as a supplement to my bard back when I did: SW is a standalone skill for the most part.
Nowadays, I do not use a SW bard.... nor do I play on Atlantic. I play on Siege and, though I didn't expect to make or even like a bard on this shard, I have found that the shards limitations give birth to interesting and fun templates. For me,
this is such a fun template; here is what it looks like:
120 Wrestling
120 Musicianship
120 Discordance
120 Provocation
120 Peacemaking
120 Meditation
The 120 Wrestling means that one may utilize both defensive & offensive ability... the defensive ability of withstanding many hits comes in handy because there is smaller chance of having a bard spellsong knocked off, and the offensive ability means that one may spam disarm, landing it often: this renders potential pk's toothless. Not to mention being able to take advantage of 45 HCI & DCI... it's a cool situation.
Maybe the above Wrestling setup doesn't look very appealing for most shards. It works nice for me and I have found myself (unexpectedly) playing a bard again, but its magic is probably Siege specific. Try going on test center and maxing all the bard skills. Next, do the same w/ SW and Med and see what that feels like (don't forget the level 6 arcane focus & to stack the SDI). Really, trying each of the above in their most undiluted forms will begin to give you an idea of what you can live with and what you can't live without, thereby directing your path more and more with each step.
Bards are still cool and very much viable so it is definitely a space worth entertaining. Good luck.
