you can with hide provided you are not on the hate table already (ie, first strike or only done TA prior to the point of the SA+Hide).
Having Samurai sub will be very useful for fights that take more than say 20min. Typically it is too dangerous to have melee of any sort, but espeacially thf, TP off of mobs that require much more time than that to kill. For this reason, Acc gear isn't all that important for endgame fights when it comes to thf. Hitting for 1-10 damage per strike isn't worth the... what is it? 7TP we give in return. Even in fights that I am in for the whole duration... I typically only hit during SA or TA (SA never paired with WS, and only used when hate is stable...)
most of the equipment any job would want for endgame fights comes from endgame... so while there is some stuff you can buy, you will need to be participating to get most of what you would need.
Being an equipment whore, i have a full AGI set for TAs that are not paired with WS, a full dex set for SAs without WS, and a STR/ATK/DEX set for WS. Acc is ok for fights you can afford to TP on the mob for, but as i mentioned before it is generally preferable to obtain TP from an alternative source (local mobs/sleep pots/meditate), and even during those fights its often benificial to ballance acc with atk and str so you hit for more than 0-10

.
If you want a spesific list... I'll come up with one for you, just send me a PM =] But i think you should be able to get an idea based on what people have said by using somepages equipment search function ^^
