SCH BiS is all Daystar when it comes to the armour pieces, with a mix-up of High Allagan and Daystar for the accessories. Buying any of the soldiery armour pieces will ensure you're not going wrong and also naturally good and useful for your WHM, if you have one.

Weapon-wise, getting up to date with the relic quest can never be a bad thing - if you're going for the Animus, it's going to be a good i100 weapon for what it is worth, but it would only really shine upon being upgraded to Novus, with its customizable secondaries. I would probably use the T5 book with the ideal stats myself, if there was no access to the Ramuh book (also i100 with great itemization) or the High Allagan one, but if you're going to keep up to date with the relic quest anyway, going Animus/Novus will be good.
