If it's a reasonable size this year I'd pull a few sticks when they're ready. I love rhubarb but I only have one plant as I don't have room for more.
I put a forcing pot (you can use an upturned bucket) over the clump in the winter (you can do it now) so that the stems are protected and grow a bit earlier and are a bit sweeter.
This is not forcing in the traditional way, where you dig the roots up and expose them to frost then put them in a warm shed - if you do that then you do not crop them the following year, but just placing a pot over them does not stress the plant and I do it every year.
I just don't harvest the rhubarb after early June, to give it a chance to build up the crown for the following year.
Give it plenty of organic compost of farm yard manure as a mulch and plenty of water in the summer if we get a dry spell and it'll be fine.
Your plant probably isn't ready to divide yet - if you want another plant I'd buy one, but as I say, I find one is enough for the two of us.
