My party actually did Thistletop first as well, and it worked out fine. They dealt with Tsuto at the glassworks, but then decided the goblins were a bigger threat and went to Thistletop instead of the catacombs. To drive them back to the catacombs, I made sure there were references to Erylium (as a mentor to Nualia), the catacombs, and the runewell (My party had no idea what Erylium was, assuming it to be a person). There is also reference Erylium and her sinspawn joining in the final assault "from the catacombs beneath the town" in the war room" on the second level of Thistletop. With enough hints, it was pretty obvious too them that some whispering evil had lied dormant under Sandpoint for a long time. In fact, it had a great effect, because they rushed off to fight the goblins, only to learn they had left something more sinister back home.
You probably will want to throw in a random farm raid or two just to make sure they hit second level. If you read ahead into Skinsaw, it would even give you a great opportunity to let the PCs meet and get connected to some of the farmers who come into play in the next adventure, giving you some nice extra depth. Plus, they would pick up some XP, and either track or interrogate one of the goblins to find their way to Thistletop. (You can always move Tsuto and Ameiko to Thistetop and skip the entire glassworks.) I woud just play it loose and have fun with it – Burnt Offerings is one of the best “sandbox” adventures I have ever ran.
