There are spellbooks with +15 magery, that are event items. (I believe the max for crafted books is a couple points lower)
There are bracelets and rings with +20, but finding a useful one for your template would be hard. Best easy ones are the Crystalline ring from prism or the ring from last year's halloween event, which can now be crafted by using a different piece of jewelry that's a doom drop. It's like a crystalline ring with an additional property.
There's the Treatise on Alchemy talisman that has +5 magery.
That is +60, so far.
I believe there's a Mark of Travesty that will give you +10 magery and another skill, but again, that's a hard thing to find and harder to get it to work with your suit.
Non-magery options.
If you are an elf and can work it into your suit, you could lower natural music to 110 and add Song Woven Mantle, to get 10 more skill points.
This combination would get you 80 skill points to work with (100 with the 20 in Chiv) You'd still have to go with another 20 points of skills on jewelry or other items to get the last bard skill to 120 (as music and magery are in the same skill group). Suggest you take them from Vet, and put real skill into the bard skill.
My personal skills on a very similar template are
120 Provo (real)
120 Music (110 real, +10 on SWM)
120 Disco or Peace (swapped as needed) - (105 real, +15 on looted bracelet)
120 Taming (115 real, +5 from Talisman from Britain Library)
120 Lore (104 real, +11 from imbued ring, +5 from Talisman)
120 Vet (105 real, +15 from imbued ring)
106 Magery (61 real, +15 book, +15 imbued ring, +15 looted bracelet)
(+15 wrestling on the bracelet as well, but not all that useful, and a pain when trying to tame a pet that angers)
