If you don't use, or don't think you'll use your inner or outer chain ring, convert to a single chain ring and get rid of your front shifter, front derailleur and cable.
These small changes will be cheap and save a little weight.
While the tubeless conversion may save some weight and be beneficial in terms of mainentance, these are some pretty terrible suggestions, no offense. At most the weight savings of a front derailleur + chain ring + removed section of seatpost is << 1 lb, and probably less than 0.3 % of the total rider + weight combo. Not to mention a huge loss in functionality.
If there is nothing impeding the use, aka, too low of a high gear, not enough fork travel, ect.. I'd say upgrade nothing. If you're looking for something specific, ask away and we can help sort it out.
