Well, with rolls like that, you could build basically ANYTHING and succeed. It really depends on what you want to do, and the order you select.
If you wanted to be an all-out offensive beast, you could go with a single two-handed weapon, pick the Order of the Cockatrice, 18 Strength, 18 Constitution, other stats wherever, and just wreck things.
Alternatively, you could take a slightly different route and go for a single big turn, dual-wielding strategy. 18 Strength, 18 Charisma, 15 Dexterity, two-weapon fighting, Order of the Lion. Challenge grants bonus damage, and the Order of the Lion abilities are AWESOME if you have high Charisma.
Even MORE alternatively, if you're feeling particularly creative, you could take two levels in Paladin or one level in Cleric, put the 18s in Strength and Charisma again, and take the Order of the Star to get continual progression in Lay on Hands or Channel Positive Energy. It's not the best offensive option, but with those stats you'll still hit like a truck, and you'll have a little bit of party support. If you can deal with the Paladin code, you also get to Smite Evil 1/day (which is AWESOME), super-boost your saving throws, and can even heal yourself as a swift action, all while still being primarily a Samurai.
I recommend taking the Sword Saint archetype for all of these options, btw. Mounts can be tricky to use, and if you're a new player you may want to minimize the complexity of your character. Sword Saint gets rid of all that mount stuff in favor of better early damage, so the trade-off is pretty obvious. [/QUOTE
