Syncing can be continued even if you stop in between.. Don't worry.. it starts from the same place again..
About compiling, your specs seems very good.. Cm10.2 took me 50-55min approx on fresh builds without setting cache.. Still to compile kitkat so no idea.. But i recommend to set cache.. So first build will take time but the next ones will be real quick..
