Welcome! If you have the stock softtop you might find that you dont really need a bikini top also since the 2010-2011 tops are so easy to use and are pretty versatile. I made the mistake of buying a bikini top before buying a stock softtop and I doubt I will ever use it.
I would for sure recommend a hardtop lift. I use the Racor lift and it works great. It is also priced pretty good at Amazon. Amazon.com: Racor PHL-1R Pro HeavyLift 4-by-4-Foot Cable-Lifted Storage Rack: Home Improvement
Wheels,tires, and suspension are all great mods.
Since I have only owned my 2011 for a few months I am still figuring out what the best mods are but if you read the posts on this site they will give you plenty of ideas.
