If you cant get more than 50% of your stack in OOP then it is always advisable to flat and see a flop. In this case you can get probably 30-40% of your stack in so calling is fine. What you need to be aware of here is that your letting more people in so your postfop play has to be spot on.
UTG has a poor hand with very little nut draws. If he wants to play these hands OOP then tt is good for you.
Regarding your flop play, you need to make sure you are ahead here before you check raise. 98/88 crushes you and will get it in. Any other 9 with 3 live side cards has good equity against you. You're actually behind to villain equity wise on the flop. Your 2 and locked up AA actually are quite siginificant here as he has 17 live cards on the flop.
