yes, a tripel is an ale. no, a high abv beer doesn't need special consideration in kegging.
however, your rubbing alcohol description leads me to believe you may have some fusels or higher alcohols. though, that wouldn't generally go away with lower carbonation. puzzling. for the future, higher alcohols are more prevalent with warmer fermentation temps. so get your beer down to low 60's before you pitch the yeast, and try to keep the ferm temps below 68-70 in the future.
