Don’t fall into the trap of thinking the latest parts are needed, the’re often actually far worse,
Only replace things you’ve broken or worn past working.
7speed, 100mm forks and v brakes are good enough for anything 99% of mtbers ride.
Helmets, gloves, glasses, armour and specific cyclin clothes are rarely actually required at all either.
Run rear tyres until you can see the carcus through the tread.
