No you shouldn't be delegating anything right now. Leave that to those who have spare steem power. I honestly don't feel anyone should delegate any SP until they have at least 500sp to keep as this gives you the voting slider bar. This allows you to vote with a lower percentage then 100% and that allows you to spread the love a little.

If you have 525sp the most I would consider delegating at that time is 25. I feel it's a mistake for smaller accounts to give up power early on.

As for powering up, you need to go into your wallet. Look at the balance of steem you have and click on the balance. You will get a drop down menu. Click on Power Up

You will be able to select how much you want to power up.

and click on power up.

Next you will get a screen that lets you verify everything. Make sure you have the correct amount and then click OK.

On the next screen you will need to enter your Active Password. Make sure you are only using this password when you are on Steemit in your wallet or on a trusted connection like steemconnect.

Once you click "Sign In" your steem will be converted to Steem Power.

That is enough for one lesson. After you get this figured out as and I'll show you how to change your SBD into Steem.
