Answered I need to sort my bank out.

I agree with Meg. If you can put it in your house, do so. With your seeds, why not get rid of the low level ones and start planting the rest? You'll get levels and bank space then. As for the bank in general, sort it out into different tabs like, have one for all your skills, one for combat related stuff, one for event outfits etc. and while you do that, you can decide whether or not you actually need something or whether you can just sell/drop it.
