Welcome to EQ2!
Speaking as a tailor, you will always be well equipped and equal to most any encounter if you go with a complete new set of rare player crafted cloth every tier. These should become equip-able in the "2" level (12, 22, 32 etc) and one set (named "Tranguil") includes a big bump to your int plus a smaller bump to sta on each piece. Each tier there will be a slightly different name for the set based on the name of the rare cloth for that tier. So at level 22 for example you'll want "Tranquil Ruckas" while at level 42 you'll want "Tranquil Linen". Make sure you get the imbued version of the robe and pants from each set since the imbue gives you an extra feature on each item. (The imbued robe gives you a bonus self-heal while the imbued pants give you a bonus damage buff)
These sets may not be as **** or as 'exclusive' as some that you can chase after and (maybe) acquire through extensive raiding but they tend to be almost as good and are a whole lot easier to get!!!
