With RAmarl I use buttons like this:
B -- hard attack
A -- attack
X -- special attack / in rare occasions, Foie
L+B -- Zalure / Rafoie
L+A -- Resta
L+X -- Jellen / Razonde
I take off Zalure and/or Jellen where there's FO/HUnewearl/RAmarl around.
Shifta and Deband and Anti should be easily accessible from your shortcut menu.

-For armours, same as any other non-bot, really.
Luminous Field is the 2nd best armour in the game and is rather rare, but not too much in the right ID/place. Low Lv requirement.
Aura Field is the best if you have an Oran character, but the Lv requirement is 152.
Virus Armour: Lafuteria has excellent DFP and is made, which means that you don't have to find one, but you need online. Highest Lv requirement
Sacred Cloth, an excellent armour, has average stats, but will prevent paralysis, a true blessing, better hunt in Purplenum or Redria. Need Lv 144.
DF Field is decent, easier to find in Redria.
Guard Wave is a good start, pipable in Greennill and Oran.
Brightness Circle is easy-ish to obtain (Spirit Garment+Star Amplifier), and has the best EDK of all the armours, good for Cave/Temple, etc.
-For shields, you have mainly 4 choices:
Secure Feet, excellent EVP, looks incredibly great. Easy in Yellowboze.
Standstill Shield, excellent DFP, looks rather bad. Easy in Viridia.
Tripolic Shield, good DFP and EVP, really hard to find if you don't have online, even then, not so easy a drop.
Rico's Earring, best shield in the game, but Whitill only.
