for suspension, if your mainly doing trails and there not that tight you can go with some elkas, works duals or tripple rate shocks set-up to how you want them. or if your tight on money you can get some yfz 450 shocks and mod them to fit your shee. also you should get some 2+1 a-arms like wicked, fireball, etc. then you can send your rear shock out to get rebuilt by companies like pro pilot, tcs, works etc. thats set-up to your weight riding style. those mods alone will make it feel like a whole different bike and is definetly worth looking into. but if you dont have the money right this second for some shocks and you keep bottoming with the stockers, you can adjust the preload on the stock ones and make them stiffer so they bottom out less. hope that helped
