You can find lower life point chips from drops, they are those red looking disks with a dark center and they say LP and something else and a number with how much it'll give.
get kaioken to lvl 3 max level to reduce ep and lp reduction also the lp regen and ep regen chips are found in AH mostly, i would reccomend lvling to 70 to be able to use kaioken better
If you get good armor first then go and farm CC Battle just to get modusa so you can use it on the Gramble Machine 1 some are for lvl 1 or something it schould give scouter chip arround 800 LP on it its ^^ But good luck on CC Battle you might find someone some are stronger then the rest of lvl 36-40 PPL ^^
